NOVELTY - Moisture-permeable chemical protective fabric comprises a base layer and a graphene oxide layer arranged in sequence. The base layer includes a base material composed of fibers. A polydopamine layer coated on the surface of the fiber and a polyethyleneimine layer coated on the surface of the polydopamine layer. USE - The moisture-permeable chemical protective fabric is useful for manufacturing chemical protective clothing (claimed). ADVANTAGE - The moisture-permeable chemical protective fabric: adopts base material, which provides mechanical support for the fabric, and the polydopamine layer and the polyethyleneimine layer serve as a bridge connecting the base material and the graphene oxide film to improve the interface bonding strength between the materials; can increase the hydrophilicity of the substrate; improves the moisture permeability of the substrate, and promote perspiration; adopts graphene oxide film layer, which provides chemical protection for the fabric while allowing sweat to be discharged. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing moisture-permeable chemical protective fabric comprising (1) soaking the base material in the dopamine hydrochloride solution to obtain the surface material coated with poly-dopamine layer, (2) dipping the composite material of the surface dopamine layer in the polyethyleneimine solution, carrying out addition reaction to obtain the substrate layer, and (3) coating graphene dispersion on one side of the base layer obtained in the step (2), carrying out cross-linking reaction to obtain the moisture-permeable chemical protective fabric.
