▎ 摘　　要

NOVELTY - Preparation of hydrogel involves mixing ammonium persulfate and aqueous solution of graphene oxide to obtain graphene oxide/ammonium persulfate suspension, stirring hydroxyethyl cellulose and graphene oxide/ammonium persulfate suspension, adding acrylic acid and mixing, then pouring mixture into a mold, placing in constant temperature oven, removing mold, washing hydrogel with deionized water to remove unreacted monomers and impurities. USE - Preparation of hydrogel (claimed). ADVANTAGE - The preparation is simple and prepared highly elastic interpenetrating network hydrogel has excellent compression resistance and thermal conductivity. The hydrogel material has good compressive strength, reusability, no oil leakage, low viscosity and easy disassembly compared to existing thermally conductive media.
