▎ 摘　　要

NOVELTY - An inner skin comprises an organic-inorganic composite material comprising a metallic material and a carbon-based material (a), and a separation membrane comprising a carbon-based material (b). The metal material includes a comprising a metal-organic framework (MOF) chosen from MOF-808, UiO-66, UiO-66-NH2, UiO-67, UiO-67-NH2 and MIL-100(Fe). USE - Inner skin is used for chemical protection product and civil industrial protection product. ADVANTAGE - The inner skin provides protection product having improved durability, and weather resistance by increasing protection performance against aerosol particles and vapor-phase chemical agent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of the inner skin, which involves preparing a fiber substrate, immersing the fiber substrate in a solution comprising the metallic material to prepare a fiber substrate coated with metallic material, immersing the coated fiber substrate in a solution comprising carbon-based material to obtain a carbon-based material coating layer on the surface of the coated fiber-based material, and self-assembling by electrostatic interaction of the carbon-based material coating layer and metallic material.
