Active Interfacial Perimeter in Pt/CeO2 Catalysts with Embedding Structure for Water-Tolerant Toluene Combustion.

Supported Pt catalysts are often subjected to severe deactivation under the conditions of high temperature and water vapor in catalytic oxidation; thus, the superior stability and water-resistant ability of catalysts have great significance for the effective degradation of volatile organic compounds (VOCs). Herein, we constructed a Pt/CeO2-N catalyst with an active interfacial perimeter, in which Pt species were partially embedded in the defective CeO2-N support to prevent the sintering. A significant charge transfer between Pt species and ceria in the embedding structure occurred via the Pt-CeO2 interface, which induced the formation of a Pt4+-Ov-Ce3+ interfacial structure. Experimental research and theoretical calculations demonstrated that the active Pt4+-Ov-Ce3+ interface promoted the activation and migration of lattice oxygen, thus facilitating the participation of oxygen species in toluene oxidation. Consequently, Pt/CeO2-N showed excellent catalytic performance for toluene degradation. In situ DRIFTS and DFT calculation proved that the Pt4+-Ov-Ce3+ interfacial sites served as the intrinsic active center in the dissociation of H2O to generate ·OH, which contributed to the formation of benzaldehyde, thus remarkably improving the water-resistant property. This study provided a facile strategy for fabricating the interfacial embedding structure to enhance the catalytic activity and water tolerance for eliminating VOCs in practical application.

Development of a novel emulsified asphalt enhanced steel slag-based geopolymer foamed concrete

Steel slag-based geopolymer foamed concrete (SSGFC) provide a promising value-added and carbon-neutral strategy for the re-utilization of SS, and the strength and physical properties of SSGFC are essential to its practical application. Therefore, this study proposes to use emulsified asphalt (EA) to improve the pore structure, compressive strength, water resistance and thermal insulation properties SSGFC. Firstly, different contents of EA were added into the foaming solution to prepare modified foam, and then SSGFC samples were prepared by using modified foam and steel slag-based geopolymer. The fresh properties, microstructure, pore structure, reaction products and physical properties of SSGFC samples were investigated. The results indicate that EA can reduce the fluidity and settlement value of the paste and increase the setting time. The addition of EA leads to a decrease in hydration products, but it can reduce the average pore diameter of the SSGFC and improve its pore diameter distribution. The SSGFC sample prepared by modified foam with 10 % EA showed the best physical properties. Compared with the control group, its compressive strength increased by 21.4 %, water absorption decreased by 16.5 %, and thermal conductivity decreased by 31.3 %. Therefore, EA shows significant potential to enhance the performance of SSGFC, thus providing reliable support for its practical applications.

Konjac Glucomannan‐Based Edible Films: Method, Properties, and Applications

ABSTRACTKonjac glucomannan (KGm) has emerged as a promising candidate in the realm of sustainable packaging materials due to its biodegradability, biocompatibility, and unique chemical properties. Derived from the konjac plant tuber, KGm is primarily composed of glucose and mannose units linked by β‐1,4 glycosidic bonds, which impart high molecular weight, acetylation levels, and functional characteristics such as viscosity, gel‐forming ability, and water absorption capacity. In the food industry, KGm films serve as edible coatings on fruits and vegetables, extending shelf life by creating a protective barrier against moisture and oxygen. KGm‐based films are used in controlled release formulations, wound healing dressings, and tissue engineering scaffolds. Various manufacturing techniques such as solvent casting, microfluidic spinning, and electrospinning are used to customize the mechanical properties and structure of KGm films for specific applications. Ongoing research aims to enhance water resistance and barrier properties through innovations such as composite formulations and cross‐linking methods. Looking ahead, further developments in KGm‐based edible films hold promise for addressing environmental concerns linked to traditional plastic packaging materials.

Enhancing the water resistance properties of bamboo particleboard by reconstructing lignocellulose through carbonization treatment

Bamboo particleboards are recognized as a highly promising alternative to traditional wood particleboards owing to their short growth cycle, abundant availability, and exceptional mechanical properties. However, bamboo particleboards frequently exhibit undesirable hygroscopicity, which limits their broader applications. This study introduces a straightforward and inhibitor-free carbonization treatment method to enhance the water resistance properties of bamboo particleboards. During the carbonization process, the degradation of hemicelluloses and amorphous cellulose, combined with the condensation reactions among lignin molecules, leads to a significant reduction in the hydrophilic hydroxyl and carbonyl group content, resulting in a more compact micro-fibril structure. Concurrently, the degradation of specific macromolecules within the cell wall facilitates the crushing of bamboo during particleboard pressing, thereby reducing the macroscopic pore size between the particles in the board. When compared to the original bamboo particleboard, the moisture absorption, 24-h water absorption (at a relative humidity of 50 %), 24-h thickness swelling, and bound water content of the deep carbon bamboo particleboard decreased by 32.28 %, 81.57 %, 67.16 %, and 66.7 %, respectively, while the water contact angle increased by 88.89 %.

Natural Fibers are obtained from nature. The natural sources of these fibres can be plants, animals or minerals. We selected the plant sources as Lotus (Nelumbo nucifera). Lotus(Nelumbo nucifera) an aquatic perennial plant cultivated widely from Pallapalayam pond, Pollachi. Natural fibers have the advantages of low density, low cost, and biodegradability. Lotus fabric has the same significance but is less popular compared to other natural fibers. This fiber is a unique and luxurious natural fiber and its properties are Softness due to the fine and delicate fibers, breathability, antibacterial, moisture-wicking, UVresistant, sustainable alternative to synthetic fibers. It is used for Textiles like scarves, shawls and clothing, fishing nets and ropes because it has water resistant properties and other marine equipment, handicrafts such as baskets, bags and other woven goods, paper, medical purposes like napkins, wet wipes, sutures, absorbent core sheet, diapers etc. The industry is embracing nonwovens (pads, wipes, napkins) and single-use materials to cater to the huge demand from the consumer community. Nelumbo nucifera (Lotus) was used in their study to enhance the good medicinal property and eco- friendly in nature. Sustainability issues in textiles have an exploration of many new fibers from renewable sources. Lotus plants require minimal water and no chemicals or pesticides, making the fiber environmentally friendly. It is also naturally resistant to water and stains, making it’s a range of products.

Performances of starch foam improved by an alginate coating

This research aims to develop an environmentally friendly food packaging based on starch foam coated with alginate. The foam was coated with various concentrations of an alginate solution (0, 0.5, 1.0, 1.5, and 2.0 %w/v). The effects of these coatings on the properties of starch foam were then investigated. The results showed that the alginate coating increased the density of the starch foam. Starch foam coated with the alginate solution at a concentration of 1.0 %w/v showed the optimum flexural stress at maximum load (4.72 MPa), hardness (96), and mass loss in water (5.51 %). These results showed significant improvements in these properties by comparison with the uncoated foam. The alginate coating slightly improved the thermal stability of the starch foam and did not significantly delay the biodegradation of the starch foam in soil. In conclusion, coating starch foam with an alginate solution presents a viable approach to developing sustainable food packaging materials with enhanced mechanical and water resistance properties.

Chitosan/sodium alginate/ethyl cellulose-based multilayer film incorporated with l-ascorbic acid for improved barrier, mechanical, and antioxidant properties

A bioactive multilayer film (ML) loaded with l-Ascorbic acid (AA) was developed using chitosan (CH), sodium alginate (SA), and ethyl cellulose (EC). Various properties of the films, including morphological, hydrophobic, barrier, mechanical, optical, and antioxidant characteristics, were evaluated and compared to those of monolayer films made from each biopolymer. The cross-sectional analysis via scanning electron microscopy revealed the successful preparation of the ML film with layering of the different biopolymers. For the ML film the resulting water contact angle was observed with an average of 73.86° and the film showed water resistant properties as compared to the individual CH and SA films. The ML film showed the lowest water vapor transmission rate (WVTR) at 54.99 g·d−1·m−2 as compared to the individual films. Moreover, the ML film had the highest tensile strength at 0.56 MPa as compared to the mono-layer films including CH, SA, and EC with TS values of 0.33, 0.24 and 0.17 MPa, respectively. Furthermore, the AA-loaded ML film exhibited significantly higher DPPH scavenging activity at 66.20 %. These findings suggest that the ML film, due to its superior barrier, mechanical, and antioxidant properties has the potential for the applications in active food packaging.

Preparation and Properties of Translucent Suspension Chain Polyurethane With a Broad Damping Temperature Range at Near Room Temperature

ABSTRACTDeveloping a viscoelastic polymer damping material with a broad range of effective damping temperatures at room temperature and multiple functionalities has been a prominent research focus, possessing significant economic and social importance. Herein, the elastic main chain was synthesized using branched polyester polyol (DPH) and isophorone diisocyanate (IPDI). The suspension chain prepolymer was fabricated with monohydroxy long alkyl‐chain hydroxy silicone oil (OH‐PDMS) and IPDI. Translucent and damping branched polyurethane viscoelastic materials (BPUs) were prepared by reacting the elastic main chain and the suspension chain prepolymer with the cross‐linking agent trimethylolpropane (TMP). The influences of introducing suspension chains and their content within the polyurethane structure on the damping, mechanical, dynamic mechanical, thermomechanical, and water resistance properties of the polyurethane were comprehensively investigated. The experimental results indicate that the damping factor (Tanδmax) of polyurethane decreases from 1.17 to 0.91 with the addition of suspension chain. Then, with the increase of suspension chain content, the damping factor (Tanδmax) decreases slightly. The damping factor (Tanδmax) still reaches 0.84 with 66% suspension chain content. At the same time, the effective damping temperature range gradually increases from 56.4°C to 119.4°C. The glass transition temperature decreased from 58.9°C to 27.8°C, enhancing the damping performance at room temperature. It was discovered that introducing suspension chains with the SiOSi structure would delay the decomposition of soft segments and enhance heat resistance. Additionally, when the content of the suspension chain is raised to 66%, the hydrophobicity of polyurethane reaches the maximum level and the elongation at break attains 423% ± 12%.

Aqu‐Thermoplastics: Recycling Plastics with Water

AbstractRecycling of real waste plastics with diverse composition is extremely difficult. Herein, an eco‐friendly and easy‐to‐operate strategy is demonstrated to facilitate the recycling of plastic composites and mixtures by using only water. An aqu‐thermoplastic bioplastic (CPp‐TA) is constructed with switchable water solubility and excellent thermoplastic property from natural cellulose. CPp‐TA consisted of the cellulose main chain (C) and two functional groups, internal‐plasticizing group (Pp) and switchable group (TA). It not only has outstanding thermo‐plastic formability, water resistance, and mechanical property to satisfy the daily needs, but also can be easily recycled with water by switching to the water‐soluble state. CPp‐TA can processed into various high‐performance plastic parts, fibers, heat‐sealing packaging, transparent cups, paper‐plastic composites, and aluminum‐plastic composites by conventional thermoplastic processing methods. The obtained CPp‐TA/Al/paper composite exhibits better barrier performance than the famous Tetra Pak with a complex recycling process, and can be easily separated into CPp‐TA, Al foil, and paper by using basic aqueous solution to trigger the water solubility of CPp‐TA. Similarly, CPp‐TA can be effectively separated from plastic mixtures. The recovery yield achieves to 100%. The revolutionary aqu‐thermoplastic materials and water‐recycling strategy markedly reduce the recycling difficulty of intricate plastics and promote the sustainable development.

Preparation and characterization of modified CNC/waterborne polyurethane composite film

To improve the water resistance and mechanical performance of waterborne polyurethane, modified cellulose nanocrystal (CNC) as a kind of environmentally friendly material was added into the solution of waterborne polyurethane by the in-situ polymerization and mechanical blending way, and two different modified CNC/waterborne polyurethane composite films were prepared. The results show that due to the addition of modified CNC, the composite film prepared by in-situ polymerization way showed much better behavior in both water resistance and mechanical properties than that made by the mechanical blending method. When the content of modified CNC was 5% in the composite, the water resistance of the composite film increased by 34.6%. At the same time, the tensile property of the composite film was improved when using in-situ polymerization to fabricate the film, and the value of maximum tensile stress rose by 143.9%.

Rigid-Flexible Coupled Dendritic Molecule Doping: General Approach to Activate Commercial Polymers into Harsh Condition-Tolerant Multi-Reusable Strong Supramolecular Adhesives.

Developing functional adhesives combining strong adhesion, good recyclability and diverse harsh-condition adaptability is a grand challenge. Here, we introduce a general dendritic molecule doping strategy to activate commercial polymers into a new family of supramolecular adhesives integrating high adhesion strength, ultralow temperature, water resistant and multi-reusable properties. Our method involves rational design of a new rigid-flexible coupled dendritic molecule-M4C8OH as a versatile dopant, while simple M4C8OH doping into commercial polymers can modulate internal and external non-covalent interaction to enable H-bonding enhanced interchain cross-linking for tough cohesion along with enhanced interphase interaction. This endows 20 wt % M4C8OH-doped polycaprolactone (PCL) adhesives (PCL-M4C8OH) with improved adhesion strength on various substrates with the maximum increase up to 2.87 times that of PCL. In particular, the adhesion strengths of PCL-M4C8OH on polymethyl methacrylate at 25 °C and -196 °C reach 4.67 and 3.58 MPa-1.9 and 2.3 times those of PCL and superior to diverse commercial adhesives and most reported adhesives. PCL-M4C8OH also displays markedly-improved multi-usability and tolerance against ultralow temperature and diverse wet environments. Mechanism studies reveal the crucial role of M4C8OH molecular structures toward superior adhesion. Our method can be expanded to other polymer matrices, yielding diverse new supramolecular adhesives.

Enhanced mechanical and thermal properties of epoxy vinyl ester nanocomposites through hybridization with functionalized graphene oxide and nanoglass flakes

This study presents the preparation of epoxy vinyl ester nanocomposites based on hybrid nanofillers, namely functionalized graphene oxide and nanoglass flakes, for outstanding mechanical, thermal, and water resistance properties. Significantly, these hybrid nanocomposites exhibited considerable improvement in tensile strength and modulus, about 39 % and 52 % greater than neat resin, respectively. DSC analysis has shown that Tg increased from 108 °C for the neat resin to 130.9 °C for the FGO/FNGF hybrid nanocomposite, which confirmed an improvement in thermal stability. Water absorption tests have shown a remarkable reduction of moisture intake. Saturation moisture content decreased from 1.35 % for the neat resin to 0.53 % for the hybrid nanocomposite due to the tortuous pathways created by the hybrid fillers. The rheological studies confirmed that better filler dispersion and interfacial bonding are achieved, which is a 34 % increase in the storage modulus with respect to neat resin. SEM studies showed homogeneous distribution of fillers with good filler-matrix adhesion in the case of the hybrid system. The studies thus confirm FGO and FNGF synergies in reinforcement of epoxy vinyl ester nanocomposites for high-performance applications in hostile environments.

Facile fabrication of a starch-based wood adhesive showcasing water resistance, flame retardancy, and antibacterial properties via a dual crosslinking strategy

The demand for non-toxic, environmentally friendly, easily processable, water-resistant, flame-retardant and antimicrobial adhesives in the wood processing industry is becoming increasingly urgent. Few adhesives can possess these functions altogether while being synthesized easily. This paper presents a one-pot process utilizing corn starch, sodium hypochlorite, itaconic acid, and borax to synthesize a starch-based adhesive with dual crosslinking. Initial crosslinking takes place between the carboxyl groups of itaconic acid and hydroxyl groups on oxidized starch due to the formation of ester bonds. Secondary crosslinking by borate ester bonds occurs between starch hydroxyl groups and boric acid. The entire reaction process is environmentally benign, generating no waste, with all reactants converted into final products, aligning with “green” chemistry principles. When used to bond wooden boards, this adhesive achieved a dry shear strength of 5.34 ± 0.24 MPa, and a wet shear strength of 1.22 ± 0.06 MPa after soaking in water. Additionally, this starch-based adhesive exhibited antibacterial properties against Escherichia coli (ATCC 8739) and Staphylococcus aureus. Moreover, with borax incorporated, the adhesive demonstrated flame-retardancy. The limiting oxygen index for bonded wooden boards was 30.9 %, qualifying it as a flame-retardant material. These multiple functions render it promising for applications in the wood processing industry.

A sustainable black liquor-based carbon scavenger to promote urea formaldehyde as green wood adhesive with low formaldehyde emission

The current study focuses on finding an ecological method to dispose of black liquors (BLs), containing lignin macromolecules, which are produced as byproducts of rice straw-based paper production. In addition to maximizing their value as precursors in the preparation of novel formaldehyde scavengers to avoid the environmental risks associated with using urea formaldehyde in agro-wood composites. To optimize the route, various black liquors are prepared from pulping of rice straw by different pulping agents (alkali, neutral, acidic and kraft reagents) used as additions or precursors for carbon compounds. Elemental analysis, thermogravimetric analysis [TGA], Fourier transform infrared [FTIR] and scanning electron microscope (SEM), are the techniques used to characterize the BLs; while the gel time, bond strength, and differential scanning calorimetry (DSC) methodologies are applied to determine the impact of black liquor (BL) and black liquor‑carbon nanostructures (BL-CNSs) on performance of urea formaldehyde (UF) adhesive. The behavior of the investigated BL-CNSs as HCHO-scavengers is assessed from their affinity to capture the HCHO, and reduction of free-HCHO in UF-palm fibers agro-composites. BL-CNSs, as novel scavengers, exhibit promising properties where the bonding strength of BL-CNSs-UF adhesives increased to 19.7 MPa even though the UF was only 8.4 MPa. Moreover, the formaldehyde adsorption capacity ranges from 35.4 to 63.6 mg/g as well as lowering the gel time. It is interesting to note that the investigated scavengers not only reduced the free-HCHO of composites by about 40–91 %, but also enhancement in their mechanical and water resistance properties; where the modulus of rupture (MOR), internal bond (IB) and reduction in thickness swelling improved to about 50 % and 83.3 %, and 38.8 %, respectively. According to the American National Standards Institute (ANSI) standard these new scavengers, especially from BL of neutral pulping, permit the production of an eco-board (E1) with static bending exceeding the H-3 class.

Comparison of soil improvement techniques on the development of efficient consolidation response

A comprehensive experimental program including two distinct series of consolidation tests was performed on clay specimens prepared at different dry weight proportions including 0%, 1%, 2.5%, 5%, 7.5%, 10% polypropylene fiber or lime by weight mixed with clayey soil. Fiber inclusion into clay resulted in enhancement of compressive strength characteristics, improvement of hydraulic properties that is an advantage for modification of stability and durability properties of clayey soil under loads. Similarly, the higher hydraulic conductivity of clay resulted that will shorthen duration of consolidation settlement, hence, eventually influence completion of plastic consolidation deformation favorably for soft clays. Lime-treatment on clay specimens showed that the compressibility properties are improved such that the strength of clay against loading enhances, exhibits less consolidation deformation under load owing to increase in lime content. On the other hand, clay becomes highly impermeable, displays substantially larger water-resistant properties because of increased lime mass proportion (i.e. time-extension) in clayey soil that results in prolongation of expulsion of excess porewater pressure from clay due to load application, relevant induced stresses. Fiber-inclusion resulted in exhibiting logarithmic decrement with a mild rate of decline while lime-treatment led to exponential reduction with a sharp rate of drop for compression index (Cc), compressibility coefficient (αv), volume compressibility coefficient (mv). Further, fiber-inclusion stimulated exponential and quadratical increment whereas lime-treatment induced exponential decrement for coefficient of consolidation (cv), hydraulic conductivity (k), respectively. As a result, the Cc, αv, mv enhanced on the order of within 10 at average of 80% to 90% with a minimum of 70% by value for both fiber-reinforcement and lime-stabilization soil-stabilization techniques. The cv, k improved on the order of within 10 at average of 75% to 85% by value for fiber-reinforcement whereas dis-improved on the order of within 10 at average of 70% to 80% by value for lime-stabilization.

Optimization of a Low Surface Energy Coating for Enhanced Water Resistance and Condensation Suppression.

This study focuses on formulating a low-surface-energy, water-resistant, and anti-condensation coating utilizing a fluorocarbon and acrylic resins composite (FAC), enhanced by six functional additives: antistatic agents, water-repellent agents, nanofillers, anti-mold and anti-algae agent, leveling agents, and wetting and dispersing agents. An orthogonal experimental design was implemented to systematically investigate the effects of varying concentrations of these additives on the surface tension of the coating. The results show that the optimized combination of fluorocarbon and acrylic resins composite (OFAC)with functional additives significantly reduces the surface tension, thereby improving both water resistance and anti-condensation properties. This research advances the development of more efficient surface treatment technologies, particularly for applications requiring enhanced water resistance and anti-condensation performance.

Effect of aminolysis treatment on self-healing properties and printing potentialities of banana peel and edible wax based biodegradable film

Cellulose-based materials are a viable alternative to petroleum-based sources; however, the practical applicability of cellulose films is severely limited by their poor hydrophobicity. This study explores the development of hydrophobic films with self-healing properties through the incorporation of natural wax into a cellulose matrix. Different formulations of films were developed varying the concentration of glycerol (0 % to 3.5 % v/v) and aminolysis treatment. Printability property, rubbing, acid, and water resistance property of the film were also evaluated. The self-healing efficiency of the films varied from around 30 % to 80 % based on variations in glycerol and aminolysis treatment provided. Aminolysis-treated films showed enhanced self-healing properties (Self-healing efficiency ∼77 %) compared to the control films. The films were characterized for their physical, mechanical, barrier, and thermal properties and it was found that 1.5 % had superior properties compared to other compositions. Printability properties showed that aminolysis-treated films had better wetting properties (WCA ∼ 74.46°) with a peak tact force of 8.1 N. This signifies aminolysis-treated films had better ink absorption and adhesion properties, which confirms the printability nature of the films. This study highlights the potential applications of biodegradable self-healing based film, applications with a scope of resolving environmental problems by replacing petrochemical plastics.

Development of carboxymethyl cellulose/starch films enriched with ZnO-NPs and anthocyanins for antimicrobial and pH-indicating food packaging

Active packaging, which can monitor food freshness and extend the shelf life, has gained significant attention in recent years. This study aims to develop a novel carboxymethyl cellulose (CMC)/starch/anthocyanins/ZnO active films with enhanced properties and specific functionalities. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) revealed that the addition of anthocyanins and nano-ZnO particles (ZnO-NPs) led to heterogeneous microstructures and a slight decrease in the crystallinity. Fourier transform infrared spectroscopy (FTIR) indicated that there were no chemical interactions among film components. Active films containing ZnO-NPs exhibited improved ductility, as well as enhanced light barrier and water resistance properties. Notably, a shift from hydrophilic to hydrophobic behavior of the films was observed with high ZnO-NP content, as evidenced by a significant increase in the water contact angle (from 63.44° to 114.22°). Furthermore, the presence of only 1 % ZnO-NPs resulted in efficient inhibition of Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) growth. Moreover, active films containing both anthocyanins and ZnO-NPs were highly sensitive to pH changes in buffer solutions (pH 2–11). Based on the results, a recommended film formulation for future active packaging applications is a 80:20 CMC/starch blend with 3 % ZnO-NPs and 0.1 g anthocyanins.

Improved interfacial compatibility between unsaturated polyester resin and rice straw fibers after non-washing treatment with Ca(OH)2

The agricultural industry produces a substantial volume of rice straw (RS) annually, highlighting the importance of recycling RS for sustainable materials. However, the poor interfacial compatibility between RS and polymers often leads to drawbacks in their composites, such as water-swelling and limited tensile strength. Here, we propose a novel approach using Ca(OH)2 that offers several distinct advantages: enhancement of interfacial compatibility, elimination of the need for water washing, and formation of calcified hybrid particles on fiber surfaces by capturing CO2 from the atmosphere. The non-washing calcified rice straw (NCRS) fibers were used to fabricate composites with unsaturated polyester resin (UPR), resulting in NCRS/UPR composites exhibiting significant enhancements in water resistance and mechanical properties compared to RS/UPR composites. The NCRS/UPR composites achieved a water absorption rate below 25 %, thickness swelling rate below 10 %, and tensile strength of 19.9 MPa. This work comprehensively explored the mechanism underlying these achievements through experimental studies. Findings suggest that CaCO3 particles involving with released lignin act as an interfacial bridge between RS fiber surface and UPR, resulting in significantly improved properties. This approach demonstrates promising prospects as a simple and eco-friendly methodology for manufacturing RS-based composite materials.

The preparation and construction of biomimetic mineralization compatible interface of wood fiber/foamed magnesium oxychloride lightweight composites

The purpose of this study is to improve the application performance of foamed magnesium oxychloride cement (FMOC) and solve the problem of poor interfacial compatibility between the organic-inorganic interface of traditional inorganic composite materials. Inspired by the adhesion mechanism of barnacles to inorganic substrates through amyloid nanofibers and phosphoprotein, a simple green method was proposed to improve the strength and water resistance of the system. The FMOC composites (30×30×30 mm) were prepared by adding wood flour (WF) and phytic acid (PA) to the mixture of magnesium oxide and magnesium chloride. The influences of WF and PA on the compressive strength, composition, microstructure, pore structure, water resistance and flame retardant properties of FMOC were investigated. WF was used as a skeleton structure to induce cement particle aggregation, the PA molecule was used as a connecting bridge to activate the fiber skeleton to increase the active sites, and promote crystal nucleation and aggregation through hydrogen and ionic bond interactions to construct the biomimetic mineralized structure. The results show that the introduction of PA improves the compressive strength and water resistance of the FMOC/WF/PA composite system. When the PA addition amount is 0.8 %, the compressive strength of FMOC/WF/PA-0.8 % composites reached 6.64 MPa, which was 3 times compared to the FMOC composites. The softening coefficient and water absorption of the obtained FMOC/WF/PA-0.8 % composites were 0.81 and 13.84 %, respectively, which were superior to FMOC composites and presented better behavior in water resistance. Meanwhile, the modified composites have more stable pore structure and flame retardant properties, thus these green FMOC/WF/PA composites displayed potential application value in building energy conservation, aerospace and other fields.
