Effects of processing temperature, pressure, and fiber volume fraction on mechanical and morphological behaviors of fully-recyclable uni-directional thermoplastic polymer-fiber-reinforced polymers

This work explores a type of composite called thermoplastic polymer-fiber-reinforced polymers (PFRPs), often referred to as self-reinforced composites (SRCs). A representative PFRP was exemplified using unidirectional (UD) ultra-high-molecular-weight polyethylene (UHMWPE) fibers embedded in a high-density polyethylene (HDPE) matrix. The effects of compression molding temperature and pressure on the mechanical and morphological behaviors of the filament-wound PFRPs with various fiber volume fractions (Vf) were experimentally investigated.The results elucidate the evolution of morphologies and tensile properties of the PFRPs due to thermal melting, fiber misalignment from pressure, and Vf-induced structural variance, which has not been comprehensively reported yet. The highest specific tensile strength and modulus of the PFRP laminae reach 600 MPa/(g/cm3) and 31 GPa/(g/cm3), respectively. These properties are comparable to glass-/aramid-fiber-reinforced polymers (GFRPs, GFRTPs, AFRPs, and AFRTPs), with PFRPs exhibiting better ductility (specific strain at peak load ≈ 4%/(g/cm3)) than other common polymer composites.The motivation for this work was the high recyclability of PFRPs, which can be recycled by melting both the fibers and the matrix, and then reshaped them for re-manufacturing composites to maximize the efficiency in material reuse. This process simplifies the implementation of closed-loop recycling, re-manufacturing, and reuse to support sustainability in composites. This work aims to contribute to advancing thermoplastic PFRPs for their potential applications in various industries.

Ammonium persulfate oxidized nanofibrillated cellulose as a sustainable wet-end paper reinforcement additive

Nanocellulose fibers (NFCs) with specific characteristics were synthesized using the economically attractive ammonium persulfate (APS) mediated oxidation process to evaluate their potential as wet end additives in paper. The surface charge and morphology of as-synthesized NFC were tailored and characterized, and the barrier and strength properties of NFC-reinforced papers were thoroughly examined as a function of NFC contents and characteristics. The addition of two different cationic polyelectrolytes promoted electrostatic bridging between pulp fibers and maintained NFC retention above 93% regardless of the NFC nature. Results demonstrate that the presence of NFC with lower surface charge yields papers with denser fibrous network, reduced air permeability, and higher specific tensile strength. Higher surface charge NFC, on the other hand, increased floc formation and decreased NFC retention likely due to reduced dispersion and NFC agglomeration with the dual component retention system. Significantly, APS-oxidized NFC may be generally applicable as a competitive alternative to expensive and/or environmentally taxing chemicals typically employed in the manufacturing of a variety of papers and boards.

Size effect on compressive behavior of GFRP bars

In the last three decades, studies investigating the use of Glass Fiber Reinforced Polymer (GFRP) bars as an alternative to conventional steel rebars have increased due to their corrosive resistance. In addition to corrosion resistance, GFRP bars utilize high specific tensile strength, which makes them highly desirable in civil engineering applications. However, major design guidelines for GFRP-reinforced concrete structures currently do not consider their compressive contribution. Nevertheless, there is a growing trend in utilizing GFRP bars as compressive elements, driven by various studies demonstrating their ability to bear compressive loads effectively. This increasing demand underscores the need to comprehend the mechanical properties of GFRP bars, particularly in terms of their compressive behavior. Furthermore, a standardized test method to evaluate their compressive properties has not yet been developed. Addressing these gaps, this research paper focuses on investigating the influence of specimen size on the compressive strength of GFRP bars, specifically emphasizing on the compressive properties of GFRP bars. Compressive tests were conducted on GFRP specimens with varying diameters while maintaining a constant slenderness ratio. The findings from these compression tests shed light on the critical role of size in the compressive behavior of GFRP. This research emphasizes the importance of considering size as a significant parameter in designing mechanical properties for GFRP reinforcements.

Molecular-level network engineering of crosslinker towards high-performance carbon nanotube fiber

Intensive efforts are underway to integrate the distinct properties of individual carbon nanotubes (CNTs) into their assemblies and meet the growing demand for lightweight and strong materials. This study achieved CNT fibers (CNTFs) with high specific tensile strength (4.97 N/tex) and specific modulus (206.8 N/tex) by designing all-ring type bridges between CNTs. This reinforcement strategy involves suppressing the distortion of CNTs and promoting effective crosslinks within the fiber structure to increase the total inter-bundle interactions. The molecular-level network within the linking segment reduces vulnerability at the typically weak connection points and enhances load-transfer efficiency between crosslinked CNTs. In addition to improvements in mechanical properties, incorporating dopant groups in the bridge enhanced the electrical conductivity, reaching up to 2086 S m2/kg. This strategy provides straightforward access to multifunctional fibers beyond those of commercially accessible or literature-reported benchmark fibers.

Effect of Mo addition on the microstructure and high-specific tensile strength of Fe–Mn–Al–Ni–C ferrous medium-entropy alloy

Molybdenum (Mo) is known to play various roles in ferrous materials, including promoting lattice distortion and forming different types of precipitates. In this study, Mo was added to the Fe–Mn–Al–Ni–C lightweight medium-entropy alloy system, and its effects on microstructure and tensile properties were investigated in comparison to the Mo-free counterpart. The addition of Mo retarded the kinetics of recrystallization and led to the precipitation of M6C-type carbides. In terms of tensile properties, the addition of Mo improved the strength of the alloy by enhancing solid solution strengthening and precipitation strengthening. In particular, the Mo-added alloy, annealed at 800 °C for 7.5 min, exhibited a yield strength of 1274 MPa and an ultimate tensile strength of 1550 MPa. This corresponds to a specific ultimate tensile strength of approximately 218 MPa g−1 cm3, along with a uniform elongation of ∼8.5 %. The Mo content in the solid solution and the presence of Mo-rich M6C-type carbides also contributed to high back stress hardening, which enhanced the alloy's ability for strain hardening and resulted in reasonable uniform elongation.

Investigation of the mechanical properties of polyimide fiber/polyamide 12 composites printed by Multi Jet Fusion

ABSTRACT Multi Jet Fusion (MJF) has attracted extensive attention because of its ability to print support-free complex structures. However, the mechanical properties of MJF-printed polymer parts are still unsatisfactory for certain industrial requirements. Herein, by leveraging the fibre reinforcement effect and high specific strength of polyimide (PI) fibres, this work developed PI/polyamide 12 (PA12) composites with largely enhanced mechanical performance via MJF. Specifically, the tensile strength and modulus were increased by 43% and 42%, and the flexural strength and modulus were improved by 39% and 46%, respectively, compared to those of the neat PA12 parts. Furthermore, the incorporation of lightweight PI fibres endowed the composites with high specific tensile strength (67.60 kN·m/kg) and specific flexural strength (93.70 kN·m/kg), which are superior to those of MJF-printed PA12 composites reinforced with other fibres. This work provides new insights into enhancing the mechanical performance of lightweight parts printed by MJF and other powder-based techniques.

Properties and applications of bamboo and bamboo fibre composites

Bamboo fibre is a cellulose fibre that is produced from a bamboo tree. The starch-rich fibre is produced from the part of the bamboo through the process of alkaline hydrolysis. The internal structure of bamboo fibre is filled with various pores, due to which the moisture absorption is slightly higher than normal, which make it effective to generate static electricity. Bamboo fibre does not have free electrons, due to which it is antistatic. Bamboo can grow naturally without the use of pesticides as it is not eaten by insects. A wonderful bacterium is found in bamboo, called bamboo kun. The products of bamboo fibre are eco – friendly and bio – degradable having anti-bacterial properties. Bamboo has a higherspecific tensile strength than the synthetic fibres. The main properties of bamboo are their light weightiness and high tensile strength.. The main chemical components are cellulose, hemicellulose and lignin. Excess of lignin reduces the tensile strength of bamboo, hence currently work is being done to reduce the amount of lignin. The bamboo fibres can be used in many forms in the engineering products. The natural structure of bamboo and their excellent mechanical properties demonstrate the usefulness of bamboo fibres. Bamboo fibre is a natural orogenic product, it is used in the textile industry, paper industry,constructionindustry, automobileandsports goods in form of composite materials due to the excellent properties of bamboo. The development and use of natural fibre has become a centre of research. In this work discusses about internal and external structure of bamboo fibre, the factors that influence their mechanical properties and applications of the bamboo and bamboo fibres.

Highly conductive and mechanically strong metal-free carbon nanotube composite fibers with self-doped polyaniline

Individual carbon nanotubes (CNTs) have gained popularity as lightweight wire materials due to their high electrical conductivity and low density than that of copper wires. Despite intensive research on light-weight and highly conductive CNT fibers, the bulk properties of CNT assemblies are inferior to those of metal wires in terms of electrical conductivity. Herein, we propose a method to increase the specific electrical conductivity of CNT fibers with polyaniline (PANI). The structure and physical properties of the CNT fibers are precisely controlled by optimizing the PANI content through a simple and effective solution process. PANI is considered to enhance CNT orientation, decrease voids, and dope the CNT fibers, resulting in a better electron flow in the fibers. The developed composite fiber with 5 wt% PANI demonstrated remarkable specific electrical conductivity of 6,200 ± 160 S m2/kg (11.9 MS/m) (max: 6,360 S m2/kg), an improvement of 16% above as-spun CNT fiber. Simultaneously, the mechanical properties increased by 27%, yielding a high specific tensile strength of 2.63 ± 0.10 N/tex (5.05 GPa). Furthermore, the toughness improved to 79.5 J/g, approximately a 1.8 times improvement over that of the CNT fiber. The addition of a small amount of PANI to CNT fibers has led to significant improvements in electrical and mechanical properties, which can provide insights into research on the CNT fiber field.

Ion-Beam Surface Modification of Carbon Fibers

Carbon fibers are used in the production of automobiles, airplanes, sporting goods, energy, and biomedicine due to their unique properties such as high specific strength, high specific tensile strength, low coefficient of thermal expansion, and low density. The research and development of both the technology of carbon fibers production and their modification for a wide range of applications have been and remain relevant. The summary of the accumulated experience in the modification of carbon fibers shows that ion-beam treatment allows to obtain a variety of geometry of the developed surface topography, in particular, whisker-shaped and corrugated oriented across or along the fiber. Such processing compares favorably with ordinary fiber whiskering both by a variety of geometry of the composite interface, and by the absence of the problem of whisker-fiber adhesion. Ion-beam treatment also makes it possible to modify the surface layer structure from amorphized to ordered with different degrees of graphitization. Irradiation with chemically active ions leads to functionalization of carbon fiber due to formation, for example, of nitrides and carbon oxides. The choice of nitrogen ions for the technology of carbon-carbon and carbon-ceramic composites seems to be more preferable due to less stringent requirements for the temperature of the irradiated fiber. For ion-beam corrugation of polyacrylonitrile-based carbon fiber surface, only its heating above the temperature of dynamic annealing of radiation damage is required. The use of helium ions in technological plasma acceleration systems leads to a significant efficiency increase in ion-beam processing.

Mechanical response of fibre metal laminates (FMLs) under low to intermediate strain rate tension

• Young’s modulus of FMLs was observed to be strain rate insensitive. • Tensile strength of aluminium-based FMLs was found to be sensitive to strain rate. • Specific tensile properties of FMLs were significantly improved over pure metals. • Titanium-based FMLs had higher specific strength but lower SEA than aluminium-based FMLs. Fibre metal laminates (FMLs) are increasingly employed in various industries for their exceptional mechanical properties. Quasi-static tensile and flexural properties, fatigue performance and impact resistance of FMLs have been extensively investigated in the past. However, research on the intermediate strain rate range is still limited. This paper experimentally investigated the influence of strain rate on the tensile failure and mechanical response of self-made titanium- and aluminium-based FMLs at strain rates up to 10 2 s -1 . The results showed that, aluminium-based FMLs showed three-stage failure patterns, similar to that of the quasi-static tension. For titanium-based FMLs, only two stages were found in the stress-strain curves for all the strain rates. The strain rate had negligible influence on the Young’s modulus of all FMLs, the tensile strength and energy absorption capacity of titanium-based FMLs. However, the tensile strength and energy absorption capacity of aluminium-based FMLs were slightly strain rate sensitive. It was also found that titanium-based FMLs had higher specific tensile strength but lower specific energy absorption than aluminium-based FMLs at all strain rates.

The Armor of the Chinese Sturgeon: A Study of the Microstructure and Mechanical Properties of the Ventral Bony Plates.

Benefiting from their unique morphological characteristics and structural properties, the ventral bony plates of the Chinese sturgeon are excellent biological protective tissue. In this work, we studied the micro- and macro-morphology and mechanical properties of the ventral bony plates of the Chinese sturgeon to elucidate the special protective mechanisms of the bony plates. Experiments involving scanning electron microscopy and energy-dispersive X-ray spectroscopy revealed that the bony plates possess a hierarchical structure and a ridge-like shape. This structure comprises a surface layer containing mineralized nanocrystals and an internal layer containing mineralized collagen fibers. From the surface layer to the internal layer, the degree of mineralization decreases gradually. Nanoindentation, tension, and compression tests demonstrated that the bony plates feature excellent mechanical properties and a high specific tensile strength comparable to that of stainless steel. Moreover, water can significantly improve the fracture toughness and deformability of the bony plates and effectively enhance the damage tolerance of the structures. The obtained results concerning the microstructure-property-function relationships of the ventral bony plates of the Chinese sturgeon may provide novel insights for designing protective structures that are both lightweight and high strength.

A lightweight orthorhombic-phase strengthened TiZrVNbAl multicomponent intermetallic alloy with promising ambient ductility and high-temperature strength

High-temperature alloy with good ambient ductility, high elevated-temperature strength and low density is desired for industrial application. Here, a novel lightweight TiZrVNbAl multicomponent intermetallic alloy with good combination of ambient ductility and high-temperature strength was developed. The designed alloy is composed of multicomponent B2 intermetallic matrix and dispersed micro-scale orthorhombic-phase (O-phase) precipitates. The multicomponent B2 intermetallic matrix can undergo plastic deformation through the mixture of planar and wavy slip of b = a<111> and b = a<001> dislocations, while the O-phase deforms by producing dislocation and stacking faults. Moreover, the O-phase can effectively contribute to strength by impeding dislocation motion at elevated temperatures (600 °C–800 °C). Consequently, the TiZrVNbAl alloy exhibits a large elongation of ∼14%, high specific tensile yield strength of ∼171.2 MPa g/cm3 at room temperature and a high specific compressive strength of ∼62.3 MPa g/cm3 at 800 °C. The present results will give new insights into the development of lightweight ductile high-temperature alloys.

Lignocellulosic nanomaterials production from wheat straw via peracetic acid pretreatment and their application in plastic composites

Cellulose nanofibrils are typically prepared from high-purity bleached pulp through harsh chemical treatments (e.g., TEMPO oxidation), resulting in high costs and environmental impact. In this work, we utilize inexpensive wheat straw feedstock and alkaline peroxide pulping followed by mild peracetic acid (PAA) pretreatment to produce lignocellulosic nanomaterials (nano and microfibrils) with potential bioplastics applications. PAA was chosen due to its biodegradability, non-toxicity, and high reaction selectivity. As-synthesized lignocellulosic nanomaterials were thoroughly characterized and compared to nanofibrils produced via TEMPO oxidation pretreatment and then applied as reinforcing agents in plastic composites. A remarkable case of simultaneous strengthening and toughening of the polymer nanocomposite was achieved with high specific tensile strength (up to 59.5 MPa g−1 cm3), elastic modulus (up to 2.6 GPa g−1 cm3), and fracture strain (up to 138 %). This work is a comprehensive investigation of all process steps involved in lignocellulosic nanomaterials production, from original residue feedstock to final product application.

Reduced graphene oxide/cellulose nanocrystal composite films with high specific capacitance and tensile strength

Due to the environmental degradation and energy depletion, the strategy for fabricating high-performance supercapacitor electrode materials based on graphene and nanocellulose has received great attention. Herein, an environmentally friendly reduced graphene oxide (RGO)/cellulose nanocrystal (CNC) composite conductive film was prepared using L-ascorbic acid (L-AA) as the reductant of graphene oxide (GO). Based on chemical structure analysis, L-AA was proved to be an effective reductant to remove oxygen containing groups of GO. Through microstructure observation, a unique stacking structure of CNC and RGO was observed, which could be largely attributed to the hydrogen bond interaction. Furthermore, the effect of CNC amount on the performance of RGO/CNC composite films was also systematically investigated. Particularly, the addition of CNC was found to exert a positive effect on the tensile strength, which might be mainly due to a mass of hydrogen bonds between the CNCs. Meanwhile, the RGO/CNC composite conductive film featured ideal electrical double-layer capacitive (EDLC) behavior, exhibiting a gravity specific capacitance of 222.5 F/g and tensile strength of 32.17 MPa at 20 wt% CNC content. Therefore, the RGO/CNC composite conductive films may hold great promise for environmentally friendly electrode materials of supercapacitors and flexible electrical devices.

Hibridne mokronamotane kompozitne cevi (aramidno vlakno/stakleno vlakno)-epoksi smola i (ugljenična vlakna/stakleno vlakno)-epoksi smola - zapreminske, mehaničke i hidraulične karakteristike

In this paper volumetric, mechanical and hydraulic characteristics of filament wound composite one fiber tubes and hybrid tubes are presented. Composite hybrid materials, produced by filament winding technology, are categorized according to different ways of classification of hybrid materials. Four fibrous reinforcement agents (glass G600, polyamide aromatic K49, carbon T300 and carbon T800) and two impregnation agent systems (epoxy 0164 and epoxy L20) are used for manufacturing of filament wound tubes. Density, tensile strength, specific tensile strength, hydraulic burst pressure and specific hydraulic burst pressure of two filament wound glass fiber/epoxy resins tubes (as starting materials) and of twelve filament wound hybrid tubes are investigated. Four highest values of tensile strength and hydraulic burst pressure are of the next schedule: hybrid tubes mark G600-T800/L20 (the highest), hybrid tubes mark G600-T800/0164, hybrid tubes mark G600-T300/L20 and hybrid tubes mark G600-K49/L20. Also, a row of four highest specific tensile strength and highest specific hydraulic burst pressure begins with hybrid tubes mark G600-T800/L20, but the schedule of the next three tubes is different due to density of aramide composite materials (hybrid tubes mark G600-K49/L20, hybrid tubes mark G600-T800/0164 and hybrid tubes mark G600-K49/0164). All filament wound tubes (single fiber tubes and hybrid tubes) with epoxy L20 have a slightly lower density value but higher values of tensile strength, specific tensile strength, hydraulic burst pressure and specific hydraulic burst pressure than appropriate tubes impregnated with epoxy 0164. Obtained results in this testing indicate and emphasize the importance of advanced reinforcing agents (aramide roving and carbon fibers), of impregnating agents (epoxy resin systems) and of the density of hybrid tubes, especially with aramide roving.

High-strength carbon nanotube fibers with near 100% purity acquired via isothermal vacuum annealing

The Fe and carbonaceous particles are the main impurities in a carbon nanotube fiber (CNTF) fabricated by the floating catalyst chemical vapor deposition (FCCVD) method, which have an adverse effect on various applications, leading to strong demand for purification process to obtain high-purity CNTFs. However, the commonly used purification methods combining oxidation and acid refluxing cannot remove the impurities thoroughly, and will introduce undesired damage onto CNT wall at the same time. Herein, we propose an efficient purification strategy involving an isothermal annealing process under high vacuum to achieve mass preparation of CNTFs with high purity and mechanical/electrical properties. The Fe and carbonaceous impurities can be almost completely removed after vacuum annealing at 1800 °C. The purified CNTFs exhibit enhanced oxidation resistance due to the removal of Fe catalyst particles. The diffusion and evaporation of Fe atoms are most likely responsible for the removal of Fe particles enclosed with graphitic shells. The purified CNTF shows a high specific tensile strength of 1.82 ± 0.04 N/tex due to the high alignment of the CNT bundles within fibers, which can retain 80% of the value for pristine CNTF. The purified CNTF exhibits similar trends of electrical conductivity as the specific tensile strength and has a high conductivity of 3.65 ± 0.11 × 105 S/m. The large-scale preparation of high-purity CNTFs with high-performance will promote the real application of CNTFs.

High-Performance Bamboo Steel Derived from Natural Bamboo.

It is highly desirable to develop green and renewable structural materials from biomaterials to replace synthetic materials involved from civil engineering to aerospace industries. Herein, we put forward a facile but effective top-down strategy to convert natural bamboo into bamboo steel. The fabrication process of bamboo steel involves the removal of lignin and hemicellulose, freeze-drying followed by epoxy infiltration, and densification combined with in situ solidification. The prepared bamboo steel is a super-strong composite material with a high specific tensile strength (302 MPa g-1 cm3), which is higher than that (227 MPa g-1 cm3) of conventional high specific strength steel. The bamboo steel demonstrates a high tensile strength of 407.6 MPa, a record flexural strength of 513.8 MPa, and a high toughness of 14.08 MJ/m3, which is improved by 360, 290, and 380% over those of natural bamboo, respectively. Particularly, the mechanical properties of the bamboo steel are the highest among the biofiber-reinforced polymer composites reported previously. The well-preserved bamboo scaffolds assure the integrity of bamboo fibers, while the densification under high pressure results in a high-fiber volume fraction with an improved hydrogen bonding among the adjacent bamboo fibers, and the epoxy resin impregnated enhances the stress transfer because of its chemical crosslinking with cellulose molecules. These endow the bamboo steel with superior mechanical performance. Furthermore, the bamboo steel demonstrates an excellent thermal insulating capability with a low thermal conductivity (about 0.29 W/mK). In addition, the bamboo steel shows a low coefficient of thermal expansion (about 6.3 × 10-6 K-1) and a very high-dimensional stability to moisture attack. The strategy of fabricating high-performance bamboo steel with green and abundant natural bamboo as raw materials is highly attractive for the sustainable development of structural engineering materials.

Comprehensive study and analysis of mechanical properties of chopped carbon fibre reinforced nylon 66 composite materials

In recent years, applications of chopped carbon fibre polymer composites have been rapidly increasing and the majority of the components made from these materials are subjected to cyclic loading. It is used for the structural parts of automobiles and aircraft due to their high mechanical properties such as light weight, high specific tensile strength, high modulus, and high specific stiffness, outstanding wear resistance, short moulding times and high recyclability. Among all composites manufacturing methods, injection moulding processes can properly control the process and ability of different volume fraction by weight percentage of chopped carbon fibre and nylon 66. It was observed from manufacturing methods that improved processability, high time efficiency, good compatibility and interface of the composite materials. Strength is calculated by rule of mixture method for chopped carbon fibre reinforced nylon 66 composites compared to carbon steel. For 30% chopped carbon fibre reinforced nylon 66 composites optimum tensile and flexural strength are observed. Similarly, for 60% chopped carbon fibre reinforced nylon 66 composites optimum compression strength are observed. The weight of composites was found to be 5.54 times lighter than carbon steel. Further, FESEM results show that for plain specimens has no surface damage. During the tensile test, most of the fibres were pulled out and some of them break out due to fracture. During the flexural test, more severe damage to fragmented carbon fibres, crushed, delaminating between carbon fibres and matrix was observed. Similarly, during compression test, strong adhesion of bonding between the chopped carbon fibres and matrix occurs, due to higher compression force, resulting in no much damage but only small groves and voids.

Nanocellulose aerogel-based porous coaxial fibers for thermal insulation

Strong, continuous, and highly porous coaxial fibers with cellulose nanofibril (CNF) aerogel core and cellulose-rich sheath were fabricated by wet-spinning hollow fibers and infusing them with aerogel precursor for high-performance thermal insulators. The sheath contained multiscale pores, including microvoids (14.5 μm) and sub-micron pores (133 nm) in bulk, as well as ca. 25–26 nm surface nanopores, to function as a template and protective sheath for the microporous CNF aerogel core. The porous coaxial fibers had many desirable qualities, including low density (0.2 g cm3), high porosity (85%), high specific tensile strength (23.5 ± 2.5 MPa g cm−3), wide working temperatures (−20 to 150 °C), continuous and large-scale producibility, as well as biodegradability. The unique combination of multiscale porous sheath and ultra-low density aerogel core synergistically minimizes heat conductivity by all three mechanisms, i.e., restrain air circulation to limit convective heat transfer, while the poor conducting cellulose permitting little conductive heat transfer and the highly crystalline aerogel cellular walls prohibit infrared radiation, effectively suppresses radiative heat transfer under extreme temperatures.

Modifications of microcrystalline cellulose (MCC), nanofibrillated cellulose (NFC), and nanocrystalline cellulose (NCC) for antimicrobial and wound healing applications

AbstractRecently, great attention has been paid to nano-composites of cellulose, due to their unique structure as a most abundant natural polymer with having exceptional properties such as renewable, biodegradable and high specific tensile strength, aspect ratio, and Young’s modulus. Prominent cellulose is naturally present in plant lignocellulosic biomass as a biocomposite made of cellulose, hemi-celluloses, lignin, etc. In addition, it can be extracted from other natural sources including bacteria, algae, and sea animals. Microcrystalline cellulose (MCC), nanocrystalline cellulose (NCC), and nanofibrillated cellulose (NFC) is an emerging renewable nanomaterial that has various applications, such as food, paper production, industrial and pharmaceutical biomaterials. The surface modification on NCC can improves its disperse ability in different solvents and its utilization in protein immobilization, tissue engineering, drug delivery, and inorganic reaction template. Therefore, based on recent studies, this review illustrated considerable progresses with addressing medicinal properties involving antimicrobial and biocompatibility of nano-cellulose (NC) in the case of wound healing.
