SPONGE FILTER FOR AIR CLEANING, AND PREPARATION METHOD OF THE SAME

摘要

Provided is a method for producing a sponge filter for purifying air using a polymer and graphene oxide or reduced graphene oxide. An antibacterial filter for deodorization is produced by the following steps: dissolving the polymer in a graphene solution and then stirring the same; freeze-drying the same after impregnating the same in a polymer sponge so as to produce a porous sponge; and treating the same with heat around 100°C. The sponge filter produced by the method has a large surface area and exhibits outstanding antibacterial properties due to well-established antibacterial properties of graphene and air-purifying functions including deodorization.
