摘　　要：刺激响应型材料是一类在环境因素刺激下,自身的某些物理或化学性质发生相应变化的材料。刺激因素包括光、温度、pH、离子强度、电场和磁场等。本文综述了近年来光和温度刺激响应型材料的研究进展,主要从光响应型水凝胶和光致变色材料的结构类型及应用概述了光响应型材料的发展;同时从温度响应型水凝胶、热致形状记忆材料和热敏变色材料几方面介绍了温度响应型材料的研究进展及应用,并展望了光和温度刺激响应型材料在多学科领域的应用前景。Stimuli-responsive materials exhibit abrupt physical or chemical property changes in response to changes in external stimuli such as light, temperature, pH, as well as ion strengths or exposure to an electric field or magnetic field. In this paper, the progress of light-stimuli responsive materials and thermally stimuli responsive materials are reviewed. The research of light-stimuli responsive materials in the fields of light responsive hydrogels and photochromic materials are described. The progress and applications about thermally sensitive hydrogels, thermally sensitive shape memory materials and thermochromic materials are introduced. The prospects of the application and research of these materials in multi- subject area are also recommended.
