“…Over the years, researchers have diligently explored various solvents in an attempt to overcome the solubility issues of chitin. Notable examples include strong acidic solution, dimethylacetamide (DMAc)-LiCl mixtures, and ionic liquids . Each of these solvents has exhibited varying degrees of success in dissolving chitin, providing viable avenues for further processing and utilization.…”

The exigency within the textile industry for molded fibers has become increasingly pronounced, owing to the coveted attributes inherent in planar fiber products, namely, their luxuriant tactile quality, ethereal weightiness, and avant-garde allure. In this investigation, we propose a pioneering methodology for the synthesis of planar chitin fibers, diverging from the conventional paradigm of spinneret design for fiber shaping. Analytical methodologies, encompassing Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and optical microscopy, were judiciously harnessed to unravel the intricacies of the fiber formation process. By subjecting chitin fibers to coagulation baths infused with phytic acid, a stratified dermalcore architecture was engendered, endowing the fibers with remarkable malleability under exogenic forces, thereby culminating in the homogeneous production of planar chitin fibers. Thorough scrutiny through optical microscopy and cross-sectional analysis substantiates the efficacy of this innovative approach. These revelations not only bestow invaluable insights into the fabrication of planar fibers but also broaden the horizons of potential chitin applications across multifarious domains.

Silk fibroin (SF) is a biodegradable protein and possesses superior skin‐friendliness, biocompatibility, low immunogenicity, and non‐toxicity. However, SF has a series of drawbacks. For example, the application of SF in water filtration is limited by its inadequate ability to adsorb heavy metal ions. It is not inherently antibacterial, making SF ineffective as a filter to eliminate airborne bacteria. SF without conductivity is not suitable for use in sensors and triboelectric nanogenerators. In tissue engineering, deficient mechanical and anti‐inflammatory properties also have an influence on the rate of wound recovery. While physical and chemical modifications will improve its application properties as well as broaden its application areas. This review describes the modification of SF by filling, blending, structural adjustment, post treatment, crosslinking, grafting, and in situ polymerization to provide it with other functional properties. Modified SF fibers prepared by various methods (e.g., wet/dry/microfluidic spinning, electrospinning) are discussed, and they can be used in water/air filtration, chemical/pressure/strain sensors, triboelectric nanogenerators, artificial skin, wound dressings, and tissue scaffolds. Finally, the development trend of the modified SF fibers is prospected. This review has a reference significance on how to use modified SF fibers to improve filtration efficiency, sensor performance, and wound recovery.
