Abstract

This review examines the chemical modifications of chitin and chitosan fibers and filaments, emphasizing their potential for diverse applications. It discusses a variety of modifications, including amidoximation, acetylation, partial deacetylation, N-maleation, N-naphthaloylation, N-halamination, grafting, oxidation, phosphorylation, sulfation, N-acylation, Schiff base formation, quaternization, nucleophilic substitution, hydroxyethylation, and ureidation transformations. These modifications significantly enhance the properties of chitin and chitosan, improving their solubility, dispersibility, hydrophobicity, environmental stability, mechanical strength, antimicrobial activity, and hemostatic capabilities, among other characteristics. By strategically tailoring these biopolymers through chemical modifications, novel materials with enhanced functionalities can be synthesized. These advanced materials are crucial for developing functional products with broad applications across various fields, spanning from biomedicine to sustainable composites.

几丁质和壳聚糖纤维和长丝的化学改性研究进展

本文综述了甲壳素和壳聚糖纤维和长丝的化学改性，强调了它们的多种应用潜力。它讨论了各种修饰，包括氨基肟化、乙酰化、部分去乙酰化、n -马来化、n -萘酰化、n -卤胺化、接枝、氧化、磷酸化、磺化、n -酰化、希夫碱形成、季铵化、亲核取代、羟乙基化和脲化转化。这些修饰显著提高了几丁质和壳聚糖的性能，改善了它们的溶解度、分散性、疏水性、环境稳定性、机械强度、抗菌活性和止血能力等特性。通过化学修饰有策略地剪裁这些生物聚合物，可以合成具有增强功能的新型材料。这些先进的材料对于开发具有广泛应用于各个领域的功能产品至关重要，从生物医学到可持续复合材料。
