刺激响应水凝胶材料的研究进展

摘要

Hydrogels are endowed with the special three-dimensional polymer network cross-linked by chemical bonds or physical nodes. Stimulus-responsive hydrogels materials exhibit the unique swollen behaviors when environment elements are changed. Recently, various hydrogels such as pH responsive, temperature responsive, light responsive properties are constructed and their responsive mechanism were investigated. In this paper, the research progress in stimulus-responsive hydrogels was reviewed according to their different stimulus conditions along with their application.%凝胶具有独特的基于化学键或物理作用交联形成的三维网状结构。刺激响应水凝胶在外界环境变化时通常展现出独特的响应性溶胀行为。近年来，科研人员构建了各种各样的 pH响应水凝胶、温度响应水凝胶和光响应水凝胶等水凝胶材料，并对其响应机制进行了研究。文章综述了近年来科研人员在刺激响应水凝胶材料的构建及响应机制研究方面开展的工作，并对刺激响应水凝胶的应用进行了展望。
