摘　　要：微凝胶是一种具有交联网络结构的聚合物胶体粒子,处于良好溶剂中的刺激响应型微凝胶会受某些外界环境的刺激,产生溶胀-消溶胀响应行为,具有快速、可逆的相变特性和较好的生物相容性。本文综述了近年来国内外微凝胶的研究现状,介绍了互穿网络型、核-壳型和含有纳米粒子的复合型微凝胶的结构、特性和制备方法,阐述了微凝胶在药物控制释放、催化反应体系、生物传感器等方面的应用,探讨了聚合物微凝胶领域的研究前景和所面临的问题。Microgels are cross-linked colloidal polymer microparticles. The stimulus-responsive microgel particles are able to swell or deswell in response to a range of environment changes. They are biocompatible, and can undergo rapid reversible phase transition. In this paper, the latest researches in this area, including the synthesis of microgels with interpenetrating network, core-shell structured microgels, and hybrid microgel particles containing inorganic nanopaticles, and the applications of microgel particles in controlled drug release, catalytic reaction, biosensor and opitical materials were summarized. The research prospects and issues faced in this field are also discussed.
