▎ 摘　　要

NOVELTY - The method for preparing graphene non-woven fabric, involves (A) immersing the non-woven fabric in the modified solution, performing surface modification, taking out and drying, (B) adding amino-modified graphene and modified non-woven fabric to aqueous solution to obtain graphene-modified nonwoven fabric, (C) washing the graphene-modified non-woven fabric, drying, and then subjecting to high-temperature treatment to obtain final product. USE - Graphene non-woven fabric for use in mask (claimed). ADVANTAGE - The graphene non-woven fabric has strong antibacterial property, low gas penetration resistance and high filtration efficiency of 99% on microparticles, and can be reused for multiple times.
