摘　　要：用一种新型的有机磷还原剂溶解羊毛,用乙二醇二缩水甘油醚(EGDE)对溶解后角蛋白大分子进行交联,发现在有机磷还原剂存在的情况下,角蛋白分子能够交联,但角蛋白溶液不能固化成膜。用透析后的蛋白液可以固化成膜,对角蛋白膜进行FTIR、SEM和XRD分析发现,在蛋白膜中蛋白大分子彼此之间发生交联。Wool was dissolved in a new organophosphorus reductant then the keratin in that solution was cross- linked with EGDE. The results show that the organophosphorus reductant wonr t interference the cross-linking reac- tion between keratin and EGDE but it will prevent froming of the keratin film. Keratin film was made from dialyzed keratin solution. FTIR, SEM and XRD of the keratin film were investigated, then it is concluded that keratin and EGDE in the keratin film are cross-linked with each other.
