▎ 摘  要

NOVELTY - Graphene coated nonwoven fabric comprises an outer layer and an inner layer. The outer layer is a graphene coated material, and the inner layer is a nonwoven fabric. The graphene coated material comprises 1-30 pts. wt. graphene, 100-150 pts. wt. polyvinylidene fluoride, 1-5 pts. wt. polyethylene and 0.1-2 pts. wt. dispersant. The weight ratio of the polyethylene and polyvinylidene chloride in the graphene coating material is 1:50-1:100. The specific surface area of the graphene is 500-1000 m2/g and a thickness of 0.55-3.74 nm. The polyvinylidene fluoride density is 1.6-1.8 cm3. The dispersant is amine salt, quaternary ammonium salt and/or pyridinium salt. USE - The fabric is useful in preparing protective clothing (claimed). ADVANTAGE - The fabric greatly enhances the mechanical performance, anti-seepage performance and flame retardant performance, and meets the use requirement of the protection clothing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene coating nonwoven fabric.
