▎ 摘　　要

NOVELTY - A graphene modified meltblown cloth comprises 0.1-0.4 wt.% graphene material, 77-85 wt.% polypropylene, 2-3 wt.% electret master batch and 10-20 wt.% modifier. USE - The graphene modified meltblown cloth is used for mask (claimed). ADVANTAGE - The graphene doped with meltblown cloth does not reunite and has good inhibitory effect on various bacteria, viruses and coronaviruses. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method for preparing graphene modified melt blown cloth comprising performing plasma modification to polypropylene powder, mixing and ball milling graphene material and modified polypropylene powder, and mixing, melting and extruding and spinning and rewinding with electret master batch and modifier; and (2) a mask comprising a three-layer structure of, from inside to outside, skin-friendly non-woven fabric layer, barrier layer, and molded non-woven fabric layer, where barrier layer is made of graphene modified melt blown cloth.
