NOVELTY - The utility model claims a graphene composite filter paper, is one first graphene, filtering paper layer, the second graphite layer composite, the graphene layer thickness on 20 nanometer to 20 micron, thereof composite filter paper avoiding big particle material leakage, at the same time increasing machine intensity of filter paper, even though lasting liquid flowing through the composite filter paper, not too easy to break.
