摘要（英）：

The invention relates to an air-permeable film composition which is formed by uniformly distributing shell-core activated carbon intercalated graphene in a PE matrix material. The air-permeable film composition is composed of, by weight, 40-70 parts of PE, 0.5-10 parts of shell-core activated carbon intercalated graphene, 28-55 parts of inorganic filler and 0.5-5 parts of auxiliary. Activated carbon intercalated graphene is taken as a core layer of shell-core activated carbon intercalated graphene, crosslinked-structure porous polymer is taken as a shell layer, and the shell-core activated carbon intercalated graphene is composed of, by mass, 10-50% of graphene, 10-45% of activated carbon and 5-47% of crosslinked-structure porous polymer, wherein graphene is one of or multiple of oxidizedgraphene, reduced graphene and expanded graphene, specific surface area of activated carbon is 1400-3800m2/g, and particle size is 200-300 meshes. CaCO3 or/and Na2SO4 is selected as the inorganic filler. The air-permeable film composition is applied in disposable absorbing products.
