超分子水凝胶的制备与应用

Preparation and Application of Supramolecular Hydrogels

水凝胶在日常生产与生活中发挥着重要作用,但传统水凝胶由于缺乏刺激响应性等动态性,无法满足日益增长的生产与生活需求。因此,制备并应用具有优异自修复性、刺激响应性以及可适应性等动态性的超分子水凝胶(SHGs)备受关注。综述了SHGs的制备与应用研究进展,系统归纳了高分子类SHGs(如聚丙烯酸SHGs、聚丙烯酰胺SHGs等)和天然高分子类SHGs(如壳聚糖SHGs、透明质酸SHGs等)的合成方法,阐述了SHGs在生物医药、柔性传感、防污材料等领域中的应用情况,最后展望了SHGs存在问题及发展趋势。

Hydrogels play an important role in daily production and life,but traditional hydrogels cannot meet the increasing production and life needs due to their lack of dynamic properties such as stimuliresponsiveness.Therefore,the preparation and application of supramolecular hydrogels(SHGs)with excellent self-healing,stimuli-responsive and adaptable dynamics has attracted considerable attention.This paper reviews the research progress in the preparation and application of SHGs,and systematically summarizes the synthesis methods of polymer SHGs(such as polyacrylic acid SHGs,polyacrylamide SHGs,etc.)and natural polymer SHGs(such as chitosan SHGs,hyaluronic acid SHGs,etc.).Besides,the application of SHGs in biomedicine,flexible sensing,antifouling materials and other fields is expounded.Finally,the existing problems and development trends of SHGs are prospected.
