摘要
蚕丝作为一种优质的天然纤维在纺织、医疗、化妆品等领域广泛应用.与此同时,为进一步提高蚕丝纤维应用价值,采用多种方式对蚕丝纤维进行改性,包括表面化学修饰、物理工艺处理、基因工程改造等.近年来,利用纳米技术改性天然纤维成为一种新的趋势,其中,通过对家蚕添食纳米颗粒被发现能够改变蚕丝纤维力学、电子、光学等多种性能,拓展了蚕丝纤维在柔性电子皮肤、医学组织工程、生物传感器等新兴领域的应用.本文将综述国内外纳米颗粒添食饲喂家蚕生产改性蚕丝的研究进展、存在问题及发展趋势,有望为未来相关领域的研究提供参考.
Abstract
Silk,as a high-quality natural fiber,is widely used in textile,medical,cosmetics and other fields.At the same time,in order to further enhance the application value of silk fibers,various methods are adopted to modify silk fibers,including surface chemical modification,physical process treatment,genetic engineering modification,etc.In recent years,the use of nanotechnology to modify natural fibers has become a new trend.Among them,it has been found that adding nanoparticles to silkworms can change the mechanical,electronic,optical and other properties of silk fibers,expanding the application of silk fibers in emerging fields such as flexible electronic skin,medical tissue engineering,and biosensors.This article will review the research progress,existing problems,and development trends of modified silk produced by feeding silkworms with nanoparticles both domestically and internationally,which is expected to provide reference for future research in related fields.
