NOVELTY - This utility model claims a graphene cellulose composite membrane, is one kind of graphene, the first nitrocellulose membrane layer, the second combination then graphene as the three layer composite membrane, the graphene layer thickness on 20 nanometer to 20 micron between, preferably graphene layer thickness on 20 nanometer to 4 micron composite film as protein transfer of solid phase support. The composite membrane can increase protein transfer to the efficiency of PVDF film, at the same time the composite membrane and increase machine intensity, make it not easy to break.
