摘　　要：天然生物材料精巧的结构和独特的功能为许多工程技术问题的解决提供了仿生学基础。人们在不断地寻求仿效对象,以期基于生物系统发展工程技术系统。角蛋白材料作为一类具有从纳米到厘米尺度上分级结构的天然生物复合材料有着与其它天然生物材料不尽相同的结构和功能,对其结构乃至超结构进行研究,探索其力学行为的微观机理,对于包括农业工程在内的众多工程领域中仿生材料和仿生系统设计具有重要意义。该文对蹄壁角蛋白、羽毛角蛋白、毛发角蛋白及爪子角蛋白材料的结构及力学性能和角蛋白材料的分析方法进行了综合评述。The smart structures and special functions of natural biomaterials provide some biomimetic clues for solving many technical problems in engineering. Ones have been finding the imitative or biomimetic objects and paying an attention to how to transfer a biological system into an engineering system. Keratin materials is a naturally biological composite material which possesses different structure and property from other biomaterials. The structure and ultrastructure of the keratin materials have considerable effects on their mechanical behavior. The understanding of the structure as well as ultrastructure of the keratin materials should be very useful to design biomimetic materials and biomimetic systems in engineering including agricultural engineering. The structures and their effects on mechanical properties of such keratin materials as hoof wall, feather, hair and claw were reviewed. The analytic methods of beratin materials were summarised as well.
