Graphene/polymer composite hydrogel thin film and preparation method thereof

摘要: The invention relates to a preparation method of graphene/polymer composite hydrogel thin film. comprises the steps performing suction filtration on graphene aqueous dispersion obtain film by taking prepared through an oxidation reduction process as raw material, and impurity removal soaking; 2) transferring soaking after into solution dissolved with polymeric monomers initiators, completing for later use; 3) out obtained in step from solution, reaction vessel, polymerization using monomers, putting water reaction, soaking, removing unreacted initiators graphene/hydrophilic polymer disclosed ensures that specific surface area can maintain relatively stable value hydrogel, has higher application values.
