摘　　要：微凝胶能够在外界刺激下改变自身尺寸,是一类重要的智能材料构筑基元。光刺激具有可远程控制、能快速切换等特点,在刺激响应性材料的设计中受到了广泛关注。将光刺激响应性基元引入到微凝胶体系,可以得到一系列具有重要应用前景的智能材料。本文综述了近年来光响应微凝胶的研究进展,总结了赋予微凝胶光响应性的四种分子设计,包括光致异构化型、光致生热型、光致(解)交联型、光致生酸型;介绍了光响应微凝胶在调光材料、药物控释、信息显示和自修复凝胶等领域的应用;展望了该领域的研究方向、发展和应用前景。Microgel can change its size under external stimuli,manifesting itself an important building block of intelligent materials. Because light stimulus enables remote control and rapid shifting,photo-responsive materials have drawn great attention of scientists. Introducing photo-responsiveness into microgel has greatly broadened the potential of applications of microgel. This review summarizes recent research progress on light-responsive microgel. Four types of light-responsive microgel are elaborated,including photo-isomerization,photo-thermal,photo-（ de） crosslinking,and photo-acidifying. Also,a wide range of applications of light-responsive microgel are reviewed,including light-tuning,drug controlled releasing,information displaying and self-healing hydrogel.At last,a brief outlook on the future development of this field is presented.
