▎ 摘　　要

NOVELTY - A filter material comprises matrix material and graphene reactive polyurethane hot melt adhesive. The graphene reactive polyurethane hot melt adhesive is distributed on the surface of the matrix material and/or in the pores of the matrix material. The graphene reactive polyurethane hot melt adhesive is distributed with a three-dimensional network structure formed by interweaving graphene oxide. The graphene reactive polyurethane hot melt adhesive exhibits a porous structure in a cured state. USE - Filter material. ADVANTAGE - The filter material uses graphene reactive polyurethane hot melt adhesive to make the filter material with excellent air permeability and filtering effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the filter material.
