▎ 摘　　要

NOVELTY - Sponge with multi-pored structure comprises graphene structure (20), which is formed inside pores and comprise multiples of micropores (21), which is located inside the pores (11). USE - Sponge with multi-pored structure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing sponge with multi-pored structure , which involves : (A) coating porous body by immersing and drying in oxidized graphene solution; (B) immersing porous body coated with oxidized graphene again in oxidized graphene solution; (C) adding =reducing agent; (D) heating to obtain graphene hydrogel in the pore; (E) lyophilizing porous body formed with graphene hydrogel to remove water contained in graphene hydrogel; and (F) forming graphene structure with multiples of micropores in pores to obtain sponge with multi-pored structure. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of sponge with multi-pored structure. Porous body (10) Inside the pores (11) Coating layer (12) Graphene structure (20) Micropores (21)
