NOVELTY - The method involves dispersing the water-soluble latex polymer to the solution to form a mixture, after adjusting the pH of solution. The neutral pin is distributed by stirring. The polymeric sponge is immersed to the mixture. The mixture of graphene and polymer adhering to the surface of sponge is dried. The polymer is selected from the group consisting of polyvinyl alcohol, melamine, and cellulose and polyurethane. USE - Method for preparing sponge filter for air cleaning. ADVANTAGE - The antibacterial property is excellent due to the containing of the graphene. The strip ability of volatile organic compound (VOC) is excellent. The inherent property of the graphene is improved effectively. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the sponge filter.
