Fabrication of multifunctional cotton fabric with “pompon mum” shaped surface by ZIF-8 for applications in oil-water separation and anti-icing

The application of metal organic framework materials (MOFs) in superhydrophobic modification has a broad prospect. In this work, a multifunctional flexible superhydrophobic cotton fabric (PSZDC) with no fluorine, high oil-water separation efficiency, and excellent anti-icing performance was prepared through the modification of cotton fabric by dopamine (DA), ZIF-8, stearic acid (SA) and polydimethylsiloxane (PDMS). SEM and 3D ultra-depth of field stereo microscope results revealed the unique “pompon mum” shaped surface of PSZDC. ATR-FTIR, XRD, and XPS analyses confirmed the composition of the hydrophobic layer. PSZDC had a water contact angle of 165.4° and showed stability in mechanical robustness and chemical resistance tests. The oil-water separation efficiency of PSZDC was close to 100 %, and the permeation flux was as high as 36,000 (L·m−2h−1). PSZDC also exhibited excellent effect in anti-icing test, which was expected to be used as ice rescue suits and oil-water separation materials. In addition, this method was universal and repeatable, as evidenced by its application to four common fabrics: nylon-6, polyester, wool, and silk.

Fabrication of Multifunctional Cotton Fabrics with Antibacterial, Hydrophobic, and Dyeing Performance.

Cotton fibers have received considerable attention owing to their functional properties. Current research endeavors have shifted toward devising straightforward and versatile approaches for modifying cotton fibers. Herein, a simple and feasible method was proposed for preparing multifunctional cotton fibers. This method entailed subjecting cotton fibers to alkaline conditions, prompting the epoxy group in epoxidized soybean oil to engage in a ring-opening reaction with the hydroxyl group in cotton fibers and the amino group in polyhexamethylene guanidine hydrochloride. Epoxidized soybean oil acted as a bridge, forming a covalent bond between polyhexamethylene guanidine hydrochloride and cotton fibers, thereby facilitating the cationization of cotton fibers. Structural changes in the modified cotton fibers were characterized using Fourier transform infrared spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and energy-dispersive X-ray spectroscopy. The modified cotton fibers were also evaluated for their dyeing, antibacterial, and hydrophobic properties. The results demonstrated that the dye exhaustion and total dye utilization of modified cotton in salt-free dyeing were much higher than those of raw cotton in conventional dyeing. The water contact angle of the modified cotton fiber reached 139.5°, and their antibacterial properties were partially improved. Importantly, this chemical modification was performed under mild conditions, highlighting its simplicity and environmentally friendly nature.

Durable multifunctional cotton fabric with superior biocidal efficacy and flame retardancy based on an ammonium phosphate N-halamine

Multifunctional textiles have become the mainstreams along with development of textile industry and the increased need of public. But a facile fabrication method with well-balance of multiple functions is still a challenge. In this work, an ammonium salt of tris(methylphosphonate)aminomethane (TAMPU), which can directly react with cellulose molecules and transform to N-halamine antibacterial structure, was easily synthesized and used to achieve multifunctional cotton fabric. As a result, the modified cotton fabric of 15.8 % weight gain exhibited excellent fire resistance with LOI value of 33.8 % and self-extinguishing behavior. Due to the good char-forming capacity of TAMPU, strong heat suppression was achieved and the peak of heat release rate (PHRR) and total heat release (THR) were decreased by 87.6 % and 60.8 %, respectively. Besides, the modified samples presented outstanding bactericidal effects, and all of S. aureus and E. coli could be inactivated within 5 min without dissolution phenomenon. Furthermore, the TAMPU-modified cotton fabric owned good washing durability and LOI value was remained at 29.8 % after 50 washing cycles. This TAMPU multifunctional modification had slight influence on the mechanical property and air permeability of cotton fabric. Thus, this work provides a convenient and friendly way to fabricate multifunctional flame-retardant and antibacterial cotton fabric.

Construction of green versatile coating integrating fireproof, electric-conduction and self-cleaning performance for cotton fabrics

The development of conductive cotton fabrics possessing superb self-cleaning and fire-proof performances exhibits vast vistas in wearable electronic devices. However, the secretion substances from human body or contaminants from the environment may interpret the normal functions of the devices and induces short-circuiting and even fire. Herein, a new strategy for the fabrication of multifunctional cotton fabrics was introduced, involving with the sequent coating of bio-based flame-retardant, conductive two-dimensional material and hydrophobic long chain alkyl silane. The multiple coating endowed the cotton fabric with a higher limited oxygen index value of 36.7% and a dramatical reduction in peak of heat release rate (74.4%) and total heat release rate (62.4%), also with a rapid self-extinguishing ability during burning. The deposition of MXene tremendously promoted the conductivity of the fabric and the coated fabric could make a steady-state electrothermal response of 129.3 °C at 5 V. Moreover, the fabric showed an excellent self-cleaning ability for common dyes and contaminants which allowed it to retain the normal functions under various conditions. The multifunctional cotton fabric designed in this work showed a high prospective in the practical applications of wearable electronics, flexible sensors, early warning, and even special membranes for extreme environments.

Durable biobased hybrid compounds: Potential modifying agents for the development of functional cotton fabrics

The advancementof antibacterial, stain-resistant, and easy-to-clean multifunctional cotton fabrics finds its scientific appeal and practical value due to their multidisciplinary uses in pharmacy, sanitation, clinics, etc. In this investigation, the cotton fabric was immersed in chitosan- vinyltriethoxy silane (Ch-VTES) and N-(2-hydroxy)propyl-3-trimethylammonium chitosan chloride- vinyltriethoxy silane (HTACC-VTES), prepared via the cost-effective sol–gel process to produce self-cleaning and antimicrobial cotton fabrics for end-uses. The Ch-VTES and HTACC-VTES modified cotton fabrics showed encouraging water contact angles of 102° and 139° respectively i.e. closer to superhydrophobicity as well as strong self-cleaning behavior without compromising the physicochemical properties of unmodified cotton fabric. Notably, the modified fabric demonstrated enchanting bacterial killing efficiency with a noticeable zone of inhibition against E. coli (17 mm for Ch-VTES and 21 mm for HTACC-VTES modified fabrics) and S. aureus (20 mm for Ch-VTES and 25 mm for HTACC-VTES modified fabrics) bacteria. Both modified cotton textiles showed an absorption peak at 1208 cm−1 (Si-O-C bending) in FTIR, suggesting that silane binds to the cotton substrate more firmly. The stability and longevity of the modified cotton fabrics with desired properties remain unchanged till 15 cycles of washing for the antibacterial test and the 20 cycles for the water contact angle. The fabricated textiles would be used for a wide range of uses, including medical applications as well as personal care products.

A photothermal cellulose-based material for rapid anti-bacteria and HCHO removal via sequential formation of MnO2 coatings and amine-quinone networks

Nowadays, with the rapid growth of population and acceleration of global urbanization, the microbial contamination on textiles and continuous formaldehyde (HCHO) releases from indoor decoration have aroused public attentions along with the textile consumption. Herein, a green, novel method for preparation of a multifunctional cotton fabric was reported, via the combination use of mussel-inspired fabrication of amine-quinone networks (AQN) and in-situ deposition of manganese dioxide (MnO2). Unlike the conventional methods under extreme conditions, in this method, the MnO2 particles were efficiently deposited on the fiber surfaces at room temperature within 30 min in the presence of reductive AQN surface composed of polyethyleneimine (PEI) and dopamine, and the MnO2-deposited cotton fabric exhibits efficient photothermal antibacterial capability against both Staphylococcus aureus and Escherichia coli, with inactivation efficiencies over 97% after 20 min of irradiation. In addition, this multi-functional fabric shows prominent UV-shielding property (UPF > 100) and HCHO purification ability, making 106.04 μg of HCHO rapidly removed within 30 min by 2.5 g of modified cotton. Therefore, we believe that the functional fabric exhibits wide applications in the fields of home textiles for antibacterial and air purification under mild conditions, and the special AQN structure can be further expanded to fabrications of other multifunctional nano-composites.

Preparation and properties of nano-MgO/HDTMS super hydrophobic multifunctional cotton

First, nano-sized magnesium oxide (MgO) particles were prepared with magnesium nitrate hexahydrate as raw material and plant extract Angelica dahurica as a protective agent and dispersant. Then, MgO nano particles (MgO NPs) were loaded on the cotton fabric surface by dipping method. Finally, using hexadecyl trimethoxysilane (HDTMS) as a modifier and ammonia as a catalyst, the cotton fabric was hydrophobically modified to prepare a super hydrophobic multifunctional cotton fabric. FTIR indicated that long carbon chain silane was successfully introduced onto cotton fabric. SEM and XRD analysis showed that the micro-nano rough structure was formed on the MgO/HDTMS/cotton fabric surface, and its crystal structure was unchanged. The water contact angle of cotton fabric modified by MgO/HDTMS reached 153°, which made it super hydrophobic. Moreover, MgO/HDTMS/cotton fabric has excellent antibacterial properties with the antibacterial rates against S. aureus and E. coli of 95.50% and 95.30%, respectively. After 10 times of cyclic washing, both the water contact angle and the antibacterial rate for S. aureus and E. coli of the fabric showed a slight decrease, which indicated that it has good washing durability.

Flame-retardant and antibacterial properties of cotton fabrics treated by epichlorohydrin-modified aramid nanofibers, ionic liquid, and Cu ion

To meet the demands of reducing the serious illness caused by the growth of bacteria and the severe life-threatening due to interior fabric fire, the attention to antibacterial flame-retardant cotton fabrics has reached an unprecedented height. In this work, a simple step-by-step dip-coating method was applied for the multifunctional cotton based on epichlorohydrin-modified aramid nanofibers (AEP), ionic liquid (IL), and CuSO4. Cot/AEP/IL/Cu exhibited low flammability with a limiting oxygen index (LOI) improving from 18.5% to 28.5% and high flame retardancy (e.g., ∼43.7% and 41.7% decline in peak heat release rate (pHRR) and total heat release rate (THR)). Noticeably, the Cot/AEP/IL/Cu revealed conspicuous smoke suppression and toxic reduction property compared with Cot/AEP/IL (e.g., ∼77.0% decline in peak smoke release rate (pSPR) and 40.5% in total CO production (TCOP)). In addition, the antibacterial property of treated cotton was investigated by the agar diffusion plate method. Due to the presence of Cu ion, Cot/AEP/IL/Cu remarkably restrains the activity of E. coli and S. aureus. This work prepared a multifunctional cotton fabric integrated with flame-retardant, smoke suppression, toxicity reduction, and antibacterial in a straightforward way, which endows promising applications in many fields.

A highly flame-retardant, agile fire-alarming and ultrasensitive cotton fabric-based piezoresistive sensor for intelligent fire system

With the high frequency of fires, multifunctional cotton fabrics with high flame retardancy and agile fire-warning ability are urgently needed. Herein, a newly cotton fabric-based piezoresistive sensor (denoted as CF@A-CNTs/APP) with intelligent fire protection and high sensitivity is proposed, which is composed of amino-functionalized carbon nanotubes (A-CNTs) and ammonium polyphosphate (APP) wrapped on cotton fabric (CF) using layer-by-layer self-assembly. The CF@A-CNTs/APP demonstrated excellent flame retardancy due to the synergistic formation of a dense flame retardant layer on the CF surface by A-CNTs and APP. The char residue of CF@A-CNTs/APP reached 44.0 wt% at 700 °C (nitrogen atmosphere), and the limiting oxygen index of CF@A-CNTs/APP was as high as 37.6%. More importantly, the CF@A-CNTs/APP triggered the fire-alarming system within 2 s. Benefiting from the pattern microstructures of double-layers CF and the high conductivity of A-CNTs, the CF@A-CNTs/APP has exhibited a high sensitivity of 3.8 kPa−1 (0 kPa-16.62 kPa). In view of outstanding flame retardancy, high sensitivity and robustness, the CF@A-CNTs/APPs could be integrated into firefighting suits or electronic skins to monitor the behavioral actions and equipment operating conditions. This work provides a novel strategy for a new generation of CF-based sensors with fire resistance and high sensitivity, and offers new insights into the preparation and application of smart fire-resistant materials in the field of the internet of things.

“One Stone Three Birds”: A multifunctional cotton fabric with favorable self-cleaning, photothermal effect and Joule heating properties

In this work, a multifunctional cotton fabric with self-cleaning property, photothermal effect, and Joule heating performance is developed by simply coating the cotton fabric with PEDOT:PSS, pen ink and PDMS. The electrical conductivity of the fabric can be effectively improved by the glycol doped PEDOT:PSS and ink modification. Joule-heating generated by the fabric’s electrical conductivity enables it to be applied to cold fields and personal thermal management, and the photothermal effect of ink modification on the fabric can be used to accelerate water evaporation and remove contaminants. Moreover, further coating with PDMS not only gives the fabric good hydrophobicity for self-cleaning, but also gives the fabric high stability against harsh conditions including organic solvents and ultraviolet radiation. This work provides a new way to expand the application range of cotton fabrics and apply them to solve various problems in different fields.

Combination of multifunctional cotton fabrics derived from different steps during one preparation process to efficiently integrate superhydrophobicity, antibacterial property and photocatalysis for multi-purpose water purification

The discharge of wastewater containing oil and dye has caused serious water pollution, and it is difficult to achieve simultaneous oil-water separation and dye degradation with a single material. Herein, two multifunctional fabrics were prepared from different steps during one preparation process for the first time, as to the best of our knowledge, by simple chemical oxidation polymerization and dipping. Ag nanoparticles were introduced by reduction of polypyrrole (PPy) after the in-situ deposition of PPy on cotton (namely, CF-PPy/Ag). Then, CF-PPy/Ag was immersed in the polydimethylsiloxane (PDMS) solution to achieve wettability modification (namely, PDMS@CF-PPy/Ag). PDMS@CF-PPy/Ag not only showed good durability and superhydrophobicity, but also own excellent antibacterial property (>99.99 %) against E. coli and S. aureus. The fabric exhibited excellent oil-water separation performance and recyclability, with a high separation efficiency (>98.5 %) after 50 cycles. Meanwhile, CF-PPy/Ag could be applied for dye degradation due to the excellent antibacterial and photocatalytic activity. The degradation efficiencies of CF-PPy/Ag for methyl blue and methyl orange were 90.1 % and 95.2 %, respectively, after 90 min of simulated sunlight irradiation. More importantly, we further designed a simple device that combined both CF-PPy/Ag and PDMS@CF-PPy/Ag, which could simultaneously achieve efficient oil-water separation and dye degradation. Therefore, we believe that the efficient strategy of combining multifunctional cotton fabrics derived from different steps during one preparation process for multi-purpose purification of water can provide a promising solution for the treatment of complex water pollution and a new idea for the collaborative application of multifunctional fabrics in the field of oil-water separation.

Multifunctional cotton fabric with directional water transport, UV protection and antibacterial properties based on tannin and laser treatment

In this study, multifunctional cotton fabric with directional water transport and excellent UV protection and antibacterial properties was prepared by persimmon tannin and laser (PT-L) treatment. Persimmon tannin (PT) treated cotton fabric was hydrophobic by forming a hydrophobic surface and constructing the micro-nano structure. The unique chemical composition and structure of the persimmon dyeing solution gave it excellent UV protection and antibacterial properties. Then the PT treated cotton fabric was dotted by a 4w laser, which gives the gradient wettability for directional water transport in the thickness direction. The water drip test proved that the droplets can be transported to the top side of the fabric through the dot area under antigravity conditions and cannot reverse penetrate. The microscopic morphology and chemical composition of the surface of cotton fabrics with different treatments were analyzed by scanning electron microscopy and Fourier transform infrared spectroscopy. Functional tests showed that the PT-L treated fabric has excellent UV protection and antibacterial properties. Stability and physical properties tests showed that PT-L treated cotton fabric has good rubbing resistance and durability without adverse effects on other properties. The preparation process is simple and effective without the use of any synthetic chemicals, which provides an innovative and green approach to the production of functional cotton fabrics.

Multifunctional Superamphiphobic Cotton Fabrics with Highly Efficient Flame Retardancy, Self-Cleaning, and Electromagnetic Interference Shielding

Here, a facile method is reported to prepare multifunctional cotton fabrics with high flame retardancy, high electrical conductivity, superamphiphobicity, and high electromagnetic shielding. The cotton fabric surface was first modified with phytic acid (PA), which promoted dehydration and carbonization of cellulose to increase flame retardancy in the process of pyrolysis. Tannic acid (TA) and 3-aminopropyltriethoxysilane (APTES) coating with nanospheres as interlayers created hierarchical roughness that facilitated the construction of superamphiphobic surfaces and provided adhesion sites for silver nanoparticles. In addition, the TA-APTES coating improved flame retardancy because the APTES-containing silicon could form silicon carbon layers to isolate heat and oxygen. Subsequently, the surface energy of the composite cotton fabric was reduced by fluorine-containing molecules. The prepared composite cotton fabric exhibited excellent superamphiphobicity with contact angles of 160.3 and 152° for water and olive oil, respectively. The conductivity and EMI shielding efficiency of the prepared composite cotton fabric reached 629.93 S/cm and 76 dB, respectively. Importantly, the composite cotton fabric maintained a relatively stable EMI shielding efficiency even after cyclic bending and abrasion tests. Moreover, the composite cotton fabric possessed a high limiting oxygen index (LOI) of 45.3% and self-extinguishing properties with the peak heat release rate (PHHR) and total heat release (THR) reduced by 73 and 67%, respectively, than the pure cotton fabric, indicating the outstanding flame retardancy.

Superhydrophobic self-extinguishing cotton fabrics for electromagnetic interference shielding and human motion detection

• Multifunctional cotton fabric has been prepared via a layer-by-layer method. • Cotton-10BL-Si shows superhydrophobic and self-extinguishing behaviors. • Cotton-10BL-Si has great potential in EMI shielding and motion sensors. • Cotton-10BL-Si shows satisfying washability and durability. Multifunctional intelligent fire-safe cotton fabric promises next-generation fire-fighting uniform and sensor applications. However, cotton fabrics' hygroscopicity and intrinsic flammability significantly impede their potential applications in industries. Herein, we report a superhydrophobic fireproof cotton fabric (PEI-APP-PEI-MXene) generated via sequential layer-by-layer deposition of polyethyleneimine (PEI), ammonium polyphosphate (APP), and titanium carbide (MXene), followed by hydrophobic treatment with silicone elastomer. Compared to untreated cotton, the treated cotton fabric with 10 polymolecular layers exhibits ∼43% and ∼42% reductions in the peak heat release rate and total heat release, respectively, a desired UL-94 V-0 rating, and a high limiting oxygen index (LOI) value of 39.5 vol.%. In addition to that, the treated fabrics displayed improved electromagnetic interference (EMI) shielding and motion-sensing abilities. The presented work provides a facile and effective surface modification approach to generate multifunctional cotton fabrics with promising practical applications.

Fabrication of Highly Efficient Flame-Retardant and Fluorine-Free Superhydrophobic Cotton Fabric by Constructing Multielement-Containing POSS@ZIF-67@PDMS Micro-Nano Hierarchical Coatings.

The facile construction of a cotton fabric with excellent flame-retardant and water-proof abilities is of great interest for multitask requirements. Herein, a nonfluorine, highly efficient, and cost-effective multifunctional cotton fabric was fabricated via sequentially depositing a novel multielement-containing flame-retardant phosphorylated octa-aminopropyl POSS (PPA-POSS) and a fluorine-free superhydrophobic coating of zeolitic imidazolate framework-67@poly(dimethylsiloxane) (ZIF-67@PDMS). Influences of the PPA-POSS concentration and ZIF-67@PDMS formula on the fire retardancy and water repellency of treated cotton were systematically investigated. The optimized flame-retardant sample CTF3 with 6.2 wt % PPA-POSS exhibited a high limiting oxygen index (LOI) of 34% and self-extinguishing ability. CTF3 was further modified with a properly formulated superhydrophobic ZIF-67@PDMS coating. CTF3-PHB2 displayed enhanced thermal stability, flame retardancy, and outstanding superhydrophobicity. Thermogravimetric analysis (TGA) results demonstrated that CTF3-PHB2 presented a high char residue of 35.9%, which was 220.5% higher than that of the control cotton (11.2%). More importantly, the heat release rate (HRR), total heat release (THR), and average effective heat of combustion (av-EHC) values of CTF3-PHB2 were significantly reduced by 51.4, 56.2, and 68.4%, respectively, compared with those of a pure cotton fabric. Moreover, CTF3-PHB2 showed superhydrophobicity (WCA > 159.3°) and good mechanical abrasion resistance. In addition, CTF3-PHB2 also showed protective abilities such as antifouling, self-cleaning, and water/oil separation performances even for strong acid/alkali mixtures. Thereby, it is believed that the PPA-POSS@ZIF-67@PDMS coating is promising for application in multifunctional textile materials.

Fabrication of chitosan-based finishing agent for flame-retardant, UV-protective, and antibacterial cotton fabrics

This study developed a simple method for synthesizing nitrogen-phosphorus-rich green multifunctional chemical agents for fire-retardant, UV-protective, and antibacterial cotton fabrics. Chitosan was obtained from chitin via deacetylation. Extracted chitosan was then chemically modified with melamine and sodium pyrophosphate as nitrogen and phosphorous sources, respectively, and glyoxal as a crosslinking agent. The structural, chemical and thermal properties of modified chitosan and multifunctional cotton fabrics were determined using FTIR, XRD, and TGA. The use of LOI and vertical flammability tests to evaluate the fire-retardant properties of treated cotton fabrics confirmed the fire retardancy imparted to the treated fabrics. The treated cotton fabrics also provided excellent UV protection and were highly effective at inhibiting the growth of tested gram-positive and gram-negative bacteria. The LOI and UPF for the highest concentration treatment were found to be more than 30 and 100 respectively whereas there was nearly 99% reduction in the bacterial colonies on treated cotton. Although the treatment had a negative impact on the mechanical properties of the fabrics, it was within acceptable limits for textile standards.

This work provides a new opportunity for integrating multiple functions onto a cotton fabric for contaminants removal and oil detection.

Bio-inspired and facile fabrication strategy of bio-based, halogen-free and superhydrophobic cotton fabrics with multi-functionality and durability

To satisfy the needs of cotton fabrics in the aspect of multi-functionality and durability, a layer-by-layer (LBL) decomposition technique was exploited, inspired by natural superhydrophobicity. Significantly, an intumescent flame retardant system consisting of bio-based phytic acid (PA) and polyethyleneimine (PEI) was used to improve the flame retardancy of cotton fabrics. Then, polydimethylsiloxane (PDMS) was deposited to reduce the surface energy of cotton fabrics, which endows the superhydrophobic properties of cotton fabrics with low adhesion. The results have shown that the water contact angle and sliding angle of as-prepared cotton fabrics reach 154° and 8°, respectively. Most of all, the multifunctional cotton fabrics have also achieved excellent self-cleaning and oil-water separation function with excellent durability and stability, which can maintain the superhydrophobicity after 24 h strong acid and alkali corrosion tests, 360 cm abrasion distance, 5 times oxygen plasma etching-restoration cycles, 5 times laundry tests, 22 times tape adhesive-peel tests and knife cutting tests. Moreover, superhydrophobic cotton fabrics exhibited good flame retardancy with self-extinguishing ability. Therefore, the superhydrophobic cotton fabrics have exhibited the characteristics of robust, environmental protection, environmental friendliness, low cost and easy preparation, which provided a feasible strategy for all-weather superhydrophobic needs in extreme environments, especially in firefighting uniforms and scenarios with high fire safety requirements.

Construction of hydrophobic fire retardant coating on cotton fabric using a layer-by-layer spray coating method

Multifunctional cotton fabric was prepared through a two-step layer-by-layer spray coating method, where the first layer of the coating comprising chitosan and ammonium phytate provided fire retardancy, and the second one with PDMS-ZnO composite imparted hydrophobicity to the fabric. A molecular dynamics (MD) simulation study was carried out to calculate interfacial adhesion of different components of the coating, based on which the sequencing of the coating layers was determined and used to prepare coated samples. The coated fabric demonstrated a significant improvement in fire retardancy through an increase in LOI from 18 % in control to 30 %, a reduction in char length from 30 cm to 7 cm, and a decrease in peak and total heat release rate values by 75 % and 33 %, respectively. The hydrophobicity of coated fabric was tested via water drop test where coated sample maintained a contact angle of 148° for up to 120 s, while the control sample showed 0°.
