NOVELTY - Oil permeable graphene sponge comprises sponge body, prepared by reacting composition containing agent A, polyisocyanate compound and graphene, where agent A includes polyol mixture, foaming agent, foam stabilizer and catalyst and polyol mixture comprises first polyol component for imparting super-lipophilicity and super-hydrophilicity to the sponge body, and first polyol component has a hydroxy value of 33-60 mgKOH/g and 50-80 mol% oxyethylene group, second polyol component is for providing sponge body with super-lipophilicity and super-hydrophilicity and second polyol component has a hydroxy value of 80-300 mgKOH/g and 50-80 mol% oxyethylene, graft polymer polyol component for increasing strength of the sponge body, tetrafunctional polyol component is used to increase the strength of the sponge body and glycerol for increasing strength of the sponge body. USE - Used as oil permeable graphene sponge. ADVANTAGE - The oil permeable graphene sponge: adopts tetrafunctional polyol component and glycerol that increases strength of the sponge body and has better super-lipophilicity.
