NOVELTY - Preparation of graphene-water-soluble polymer three-dimensional porous nanocomposite involves dissolving graphene oxide and water-soluble polymer in water in the ratio of 1:1000-1:50 and freeze-drying resultant product in mold. The mass ratio of graphene oxide and water-soluble polymer is 10:1-1:3. The water-soluble polymer is polyvinyl alcohol, polyethylene glycol or polyvinyl pyrrolidone. USE - Preparation of graphene-water-soluble polymer three-dimensional porous nanocomposite (claimed). ADVANTAGE - The method efficiently enables preparation of graphene-water-soluble polymer three-dimensional porous nanocomposite having improved properties by simple and environmentally-friendly process.
