▎ 摘  要

NOVELTY - Preparation of polymeric cryogel based on 2-hydroxyethyl methacrylate and graphene oxide, involves photopolymerizing 2-hydroxyethyl methacrylate in the presence of N,N'-methylenebisacrylamide as a crosslinking agent and 1-hydroxycyclohexyl phenyl ketone as both photopolymerization initiator and ligand, in a polymerization medium comprising an aqueous solution containing graphene oxide, at a temperature below the freezing point of mixture in the presence of UV radiation. USE - Preparation of polymeric cryogel based on 2-hydroxyethyl methacrylate and graphene oxide, used for purifying water with high organic content. ADVANTAGE - The method provides polymeric cryogel with controlled morphological characteristics.
