摘　　要：光致变色材料具有可逆的光响应特性,一直是光电子领域的研究热点.本研究将含有巯基的改性棉织物与光致变色化合物(SO)通过硫醇-烯烃点击化学共价结合在一起,制备了一种新型的光响应变色棉织物,实现了对棉织物光学性能的动态控制.所制备的光响应变色棉织物在紫外光照射下迅速由无色变为蓝色,具有光响应速度快的特点.经过20次可逆变色循环后,光响应变色织物仍保持良好的光致变色性能,这意味着所制备的光响应变色织物在智能器件和光检测方面具有很大的应用价值.此外,该光响应变色棉织物具有较好的抗紫外性,在防紫外服装领域具有较大的应用潜力.Photochromic materials with reversible photo-responsive properties have been a hot research topic in the field of optoelectronics.In this study,a novel type of photo-responsive color-changing cotton fabric was manufactured by covalent bonding of modified cotton fabric containing sulfhydryl groups and photochromic compound(SO)via thiol-olefin clickchemistry,and dynamic control of the optical properties of cotton fabrics was achieved.The photochromic fabric could change from colorless to blue with a fast light response speed under UV irradiation while presenting good fine images.After 20 reversible color-changing cycles,it still possessed photochromic properties and reusability,which meant that the prepared photochromic fabric had great value in smart devices and light detection.In addition,the light-responsive color-changing cotton fabric had good UV resistance and had great potential for application in the field of UV-protective clothing.
