▎ 摘　　要

NOVELTY - A graphene oxide and/or reduced graphene oxide membrane (130) has thermal conductivity, electroconductivity or one or more mechanical properties tuned according to a desired application of the membrane. USE - Graphene oxide and/or reduced graphene oxide membrane. ADVANTAGE - The membrane has tunable mechanical properties, thermal conductivity, electroconductivity and/or three-dimensional curvature according to desired applications and is produced in bulk at low temperature. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for production of the membrane comprising graphene materials comprising graphene oxide and/or reduced graphene oxide materials. The method involves obtaining at least one dispersion (122) comprising the graphene materials, performing reduction of the graphene oxide species in at least one of the dispersion, filtering the dispersion through a functionally shaped filter (108) media and applying pressure and heat to the filtered graphene materials. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the vacuum filtration process for the manufacture of the graphene oxide composite membrane.
