“…The synergistic application of nano-fillers alongside natural fibers within various matrix composites promises to be a transformative avenue [206]. Additionally, the incorporation of cellulose from plants, chitin from feathers, and silk into the production of green composites is expected to contribute to sustainable practices [207]. The utilization of waste materials for the manufacture of fiber composites not only addresses environmental concerns but also demonstrates a practical circular economy approach [208][209][210][211][212][213].…”

This comprehensive review explores the multifaceted world of natural fiber applications within the domain of composite materials. Natural fibers are meticulously examined in detail, considering their diverse origins, which encompass plant-derived fibers (cellulose-based), animal-derived fibers (protein-based), and even mineral-derived variations. This review conducts a profound analysis, not only scrutinizing their chemical compositions, intricate structures, and inherent physical properties but also highlighting their wide-ranging applications across various industries. The investigation extends to composites utilizing mineral or polymer matrices, delving into their synergistic interplay and the resulting material properties. Furthermore, this review does not limit itself to the intrinsic attributes of natural fibers but ventures into the realm of innovative enhancements. The exploration encompasses the augmentation of composites through the integration of natural fibers, including the incorporation of nano-fillers, offering a compelling avenue for further research and technological development. In conclusion, this review synthesizes a comprehensive understanding of the pivotal role of natural fibers in the realm of composite materials. It brings together insights from their diverse origins, intrinsic properties, and practical applications across sectors. As the final curtain is drawn, the discourse transcends the present to outline the trajectories of future work in the dynamic arena of natural fiber composites, shedding light on emerging trends that promise to shape the course of scientific and industrial advancements.

“…Silks have been primarily used for biomedical applications as they are perceived to be biocompatible, biodegradable and non-toxic [ 113 ]. It is of note that biocompatibility is not universal and must be specific to tissue and wound to encourage the correct immune response during healing [ 112 ].…”

The Formation of All-Silk Composites and Time–Temperature Superposition

2023

Extensive studies have been conducted on utilising natural fibres as reinforcement in composite production. All-polymer composites have attracted much attention because of their high strength, enhanced interfacial bonding and recyclability. Silks, as a group of natural animal fibres, possess superior properties, including biocompatibility, tunability and biodegradability. However, few review articles are found on all-silk composites, and they often lack comments on the tailoring of properties through controlling the volume fraction of the matrix. To better understand the fundamental basis of the formation of silk-based composites, this review will discuss the structure and properties of silk-based composites with a focus on employing the time–temperature superposition principle to reveal the corresponding kinetic requirements of the formation process. Additionally, a variety of applications derived from silk-based composites will be explored. The benefits and constraints of each application will be presented and discussed. This review paper will provide a useful overview of research on silk-based biomaterials.

“…Among many types of IL, imidazolium-based IL with different counter anions are frequently used for dissolution of biopolymers, especially cellulose, making it one of the most promising solvent for the fabrication of fiber materials [ 13 , 14 , 15 ]. Since its chemical structure and solute–solvent interaction mechanisms are similar to cellulose, chitin/chitosan can be completely dissolved in IL [ 16 , 17 ]. Recent scientific publications demonstrate that IL, such as 1-butyl-3-methyl-imidazolium chloride (BmimCl), 1-butyl-3-methyl-imidazolium acetate (BmimOAc), or 1-ethyl-3-methyl-imidazolium acetate (EmimOAc), are also increasingly used for the preparation of microparticles, nanofibers, gels, polymer films, and membranes from chitosan [ 18 , 19 , 20 , 21 ].…”

Pure Chitosan-Based Fibers Manufactured by a Wet Spinning Lab-Scale Process Using Ionic Liquids

Ionic liquids offer alternative methods for the sustainable processing of natural biopolymers like chitosan. The ionic liquid 1-butyl-3-methylimidazolium acetate (BmimOAc) was successfully used for manufacturing of pure chitosan-based monofilaments by a wet spinning process at lab-scale. Commercial chitosan with 90% deacetylation degree was used for the preparation of spinning dopes with solids content of 4–8 wt.%. Rheology tests were carried out for the characterization of the viscometric properties. BmimOAc was used as a solvent and deionized water as coagulation and washing medium. Optical (scanning electron microscope (SEM), light microscope) and textile physical tests were used for the evaluation of the morphological and mechanical characteristics. The manufactured chitosan monofilaments a homogeneous structure with a diameter of ~150 μm and ~30 tex yarn count. The mechanical tests show tensile strengths of 8 cN/tex at Young’s modulus up to 4.5 GPa. This work represents a principal study for the manufacturing of pure chitosan fibers from ionic liquids and provides basic knowledge for the development of a wet spinning process.
