▎ 摘　　要

NOVELTY - Multifunctional graphene/high molecular complex permeable membrane comprises (a) at least one wettable polymer chosen from moisture-conducting homopolymer, moisture-conducting copolymer and their combination, (b) graphene or graphene complex material, and (c) microporous substrate. The wettable macromolecule polymer in the microporous substrate is linked to active bond of the graphene or graphene complex material by hydrogen bond, ionic bond and/or covalent bond through a polar radical functional group to obtain product with enhanced hydrophilic-hydrophobic groups. USE - The multifunctional graphene/high molecular complex permeable membrane is useful in total heat exchanger, humidity regulator, sewage treatment, fuel cell, woven fabric, wound dressings and other permeable or filtered water (claimed). ADVANTAGE - The permeable membrane exhibits improved permeability, mechanical strength, abrasion resistance, acid and alkali resistance, anti-bacterial and anti-pollution ability, thermal conductivity, heat resistance and other characteristics, has prolonged shelf life, does no require replacement during operation, and exhibits self-cleaning ability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing the multifunctional graphene/high molecular complex permeable membrane, which involves preparing a solution by dissolving the wettable polymer in organic solvents for a predetermined time at constant temperature of 10-100 degrees C and stirring to mix uniformly, adding graphene or graphene complex material into the solution, mixing uniformly, processing the mixed solution at 10-200 degrees C and applying on one or both surfaces of the microporous substrate.
