摘　　要：采用羊毛角蛋白制备有机气凝胶,存在结构不稳定、力学性能较差等问题。为提升材料的性能,通过还原C法从废旧羊毛中提取R-角蛋白并制备角蛋白气凝胶,将特殊的三维立体结构经编间隔织物引入气凝胶中,开发出经编间隔织物增强废旧羊毛角蛋白气凝胶复合材料,并对废旧羊毛的溶解率、提取率以及材料的密度、力学及隔热性能进行测试与分析。结果表明,通过还原C法得到的羊毛溶解率为89.4%,R-角蛋白提取率为72.6%。复合材料的密度不超过28.23 mg/cm^(3),具备传统气凝胶低密的优良特性,同时经编间隔织物与角蛋白气凝胶原位复合后,材料的压缩性能显著提升,并仍具有良好的隔热性能。The preparation of organic aerogels using wool keratin generally suffers from structural instability and poor mechanical properties.To further improve the material properties,R-keratin was extracted from waste wool and prepared keratin aerogel by reduction C method,and a special three-dimensional structure of warp-knitted spacer fabric was introduced into the aerogel to develop a new warp-knitted spacer fabric-reinforced waste wool keratin aerogel composite,and the dissolution rate and extraction rate of waste wool as well as the density,the dissolution rate and extraction rate of waste wool as well as the density,mechanical and thermal insulation properties of the material were systematically tested and profiled.The results show that the dissolution rate of wool obtained by reduction C method is 89.4%,and the extraction rate of R-keratin is 72.6%.The density does not exceed 28.23 mg/cm',which has the excellent characteristics of traditional aerogel with low density,and the in-situ composite of warp-knitted spacer fabric and the keratin aerogel improves the compression performance of the material significantly,which still has good thermal insulation properties.
