NOVELTY - Preparing super-amphiphilic polyurethane foam material involves coating nano-cellulose and graphene sequentially on a polyurethane sponge, and super-amphiphilic polyurethane foam material is obtained after drying. USE - Method for preparing super-amphiphilic polyurethane foam material. ADVANTAGE - The method enables to prepare super-amphiphilic polyurethane foam material, which has a uniform distribution of nanocellulose and graphene on the surface of the continuous network skeleton of the polyurethane sponge, and has super-amphiphilic properties and absorbs water and oil at the same time and provides basis for the development of materials with surface-specific wetting properties.
