A water-responsive interpenetrating polymer network, a preparation method and use thereof are provided. The water-responsive interpenetrating polymer network comprises an interpenetrating polymer network formed by a cholesteric liquid crystal polymer and a polyionic liquid; wherein the cholesteric liquid crystal polymer is formed by polymerization of a liquid crystal mixture; and the polyionic liquid contains a hydrophilic group or is a hydrophilic salt. The interpenetrating polymer network is water responsive without needs of activation with an alkaline solution, which simplifies the preparation process, and has stable water responsiveness performance after prolonged and/or repeated exposure to water. The water-responsive interpenetrating polymer network can be used to prepare light reflective coatings and reflective devices, and has higher commercial value.
本发明提供了一种水响应互穿聚合物网络及其制备方法和用途。水响应互穿聚合物网络包括由胆甾型液晶聚合物和聚阴离子液体形成的互穿聚合物网络;其中,胆甾型液晶聚合物由液晶混合物聚合而成;聚阴离子液体含有亲水基团或为亲水盐。这种互穿聚合物网络具有水响应性,无需用碱性溶液活化,从而简化了制备过程,并且在长时间和/或反复接触水后仍具有稳定的水响应性能。水响应互穿聚合物网络可用于制备光反射涂层和反光装置,具有更高的商业价值。
