Abstract
The present disclosure provides a humidity-stiffening polymer material, and a preparation method therefor and a use thereof. The humidity-stiffening polymer material includes the following raw materials: a monomer, an ionic liquid, a salt, a cross-linking agent and an initiator, wherein the monomer includes benzyl methacrylate, the ionic liquid includes an imidazole-based ionic liquid, and the salt includes a hygroscopic salt. The method for preparing the humidity-stiffening polymer material includes: mixing the raw materials to obtain a precursor liquid, performing reaction on the mixture after degassing, and drying the mixture to obtain the humidity-stiffening polymer material. The humidity-stiffening polymer material is applied to actuators, soft robots and wearable biomedical devices based on bionic design.
