▎ 摘  要

NOVELTY - Manufacturing an ultrathin graphene/polymer film (100) involves layering a graphene layer (106) onto a polymer layer (104) to form a composite film (102). USE - Method for manufacturing an ultrathin graphene/polymer film, where films or membrane are useful for efficient separations.. ADVANTAGE - Thinner membranes enable a higher flux at the same energy cost. Thus, decreasing the thickness of a membrane reduces its stiffness and therefore reduces the amount of pressure that can be applied before membrane failure. An ultra thin composite with distinct layers of graphene and polymer with stiffness capable of withstanding continuous pressure applied during separation processes. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an ultrathin graphene/polymer film. Ultrathin graphene/polymer film (100) Composite film (102) Polymer layer (104) Graphene layer (106)
