Abstract

This work introduces an approach to creating environmentally friendly protective clothing using waste wool to produce a biodegradable and biocompatible alternative, turning environmental problems into biomedical solutions. Utilizing chemically reduced-wool keratin (KerSH), extracted from waste wool through a mild chemical reduction, blended with biocompatible gelatin and poly(2-ethyl 2-oxazoline) (PEtOx) or its hydrolyzed product poly(2-ethyl 2-oxazoline-co polyethylene imine) (PEtOx-co-PEI), it was aimed to enhance cotton fabrics with polymeric nanowebs via electrospinning. This modification provides various morphologies, including hybrid, Janus, and core–shell structures, tailored by adjusting the solvent, polymer ratios, and electrospinning conditions. The resultant nanofibrous coatings were comprehensively characterized using ATR-FTIR, ¹H-NMR, SEM, optical microscopy, and contact-angle measurements to assess their structure and properties. Consequently, this study offers a keratin-derived nanofibrous composite with potential uses in biomedical substrates such as filtration systems, biocompatible meshes, and materials for reusable surgical masks.

探索棉织物上的废羊毛衍生角蛋白纳米纤维结构：增强材料性能的电纺丝策略

这项工作介绍了一种利用废羊毛生产可生物降解和生物相容性替代品的环保型防护服的方法，从而将环境问题转化为生物医学解决方案。利用化学还原羊毛角蛋白（KerSH）（通过温和的化学还原从废羊毛中提取），与生物相容性明胶和聚（2-乙基 2-噁唑啉）（PEtOx）或其水解产物聚（2-乙基 2-噁唑啉-聚乙烯亚胺）（PEtOx-co-PEI）混合，旨在通过电纺纱技术用聚合物纳米网增强棉织物。通过调整溶剂、聚合物比例和电纺丝条件，这种改性可提供各种形态，包括混合结构、Janus 结构和核壳结构。利用 ATR-傅立叶变换红外光谱、1H-NMR、扫描电子显微镜、光学显微镜和接触角测量法对所得到的纳米纤维涂层进行了全面表征，以评估其结构和性能。因此，本研究提供了一种角蛋白衍生纳米纤维复合材料，可用于生物医学基底，如过滤系统、生物兼容网和可重复使用的手术面罩材料。
