NOVELTY - Preparing phase change gel material with variable mechanical state involves taking initiator-tetramethylethylenediamine oxidation-reduction system as initiation system, preparing poly-N-isopropylacrylamide hydrogel with three-dimensional cross-linked network structure, soaking in a lower alcohol to alcoholizing to obtain an alcohol gel, heating, melting phase change material to performing solvent replacement with the alcohol gel to obtain the phase change gel material. USE - Method for preparing phase change gel material with variable mechanical state used as energy storage material. ADVANTAGE - The prepared phase change gel material has high phase change latent heat, excellent stability, and has good elasticity and softness and as energy storage material with better mechanical property, and its shape and stiffness can be changed as needed, and it can be applied to multi-scale adhesion and attachment of various three-dimensional surface.
