Abstract
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.
