【摘要】 动物丝,特别是蜘蛛丝近年来由于其优异的综合力学性能而备受关注。但是天然动物丝的应用由于种种原因而受到各种限制,因此人们期望通过人工纺丝获得性能与天然动物丝相近的人工丝纤维。本文就采用动物丝蛋白进行人工纺丝的历史和现状,从再生蜘蛛丝蛋白、重组蜘蛛丝蛋白和再生蚕丝蛋白等方面进行综述,比较了天然动物丝和人工丝纤维的力学性能,并且探讨了人工生物模拟纺丝制备高性能人工丝纤维(超级纤维)的前景。更多还原

【Abstract】 Animal silks,especially spider silks attract considerable interest because of their excellent comprehensive mechanical properties.However,the applications of natural silks are restricted because of various reasons.Therefore, people expect to obtain artificial silk fibers that have similar performance as natural silks by artificial spinning.In this paper,the history and status quo of the artificial spinning based on silk proteins are reviewed.The mechanical properties between natural silk fibers and artificial silk fibers are also compared,and the future of the biomimic artificial spinning for the production of high-performance artificial silk fibers(superfibers) is discussed.更多还原
