Keratin is a highly multifunctional biopolymer serving various roles in nature due to its diverse material properties, wide spectrum of structural designs, and impressive performance. Keratin-based materials are mechanically robust, thermally insulating, lightweight, capable of undergoing reversible adhesion through van der Waals forces, and exhibit structural coloration and hydrophobic surfaces. Thus, they have become templates for bioinspired designs and have even been applied as a functional material for biomedical applications and environmentally sustainable fiber-reinforced composites. This review aims to highlight keratin's remarkable capabilities as a biological component, a source of design inspiration, and an engineering material. We conclude with future directions for the exploration of keratinous materials.
角蛋白是一种高度多功能的生物聚合物，由于其多样的材料特性、广泛的结构设计和出色的性能，在自然界中发挥着多种作用。基于角蛋白的材料机械性能强劲、隔热、轻质，能够通过范德华力实现可逆粘附，并且具有结构色和疏水表面。因此，它们已成为仿生设计的模板，甚至被用作生物医学应用的功能材料和环境可持续的纤维增强复合材料。本综述旨在突出角蛋白作为一种生物成分、设计灵感来源和工程材料的卓越能力。我们最后展望了角蛋白材料探索的未来方向。
