▎ 摘  要

NOVELTY - Preparing graphene-based conductive filter membrane involves putting the base film in the filter cup of the vacuum suction filter device, and then adding the graphene oxide dispersion to the filter cup. The vacuum pump of the vacuum suction filtration device is turned on, controlled the suction filtration pressure between 0.008 and 0.020 mega Pascal, performed vacuum suction filtration, and placed the prepared graphene oxide-loaded base film in a vacuum oven at 65-75 degrees C to dry. The base film loaded is placed with graphene oxide on the Petri dish, added the hydrazine hydrate solution dropwise in the Petri dish, placed it in a 65-75 degrees C oven for 15-45 minutes for fumigation, and taken out to obtain graphene-based conductivity filter membrane. USE - Method for preparing graphene-based conductive filter membrane. ADVANTAGE - The method enables to prepare graphene-based conductive filter membrane which is simple, and expected to realize industrialization, and cost-effective.
