A graphene-based membrane and a method of producing the same are disclosed. The graphene-based membrane may include a graphene-polymer composite, wherein the graphene-polymer composite may consist of an amine functionalized graphene and a polymer containing an anhydride group as a linker for linking the amine functionalized graphene to the polymer. The graphene-based membrane may be constructed of a single-layer. A method may include reacting a polymer containing an anhydride with an amine functionalized graphene in presence of a solvent to form an intermediate product; and thermal imidizing the intermediate product to form a graphene grafted polymer composite for use in fabricating a graphene-based membrane.

This invention relates to a vacuum air gap membrane distillation system for desalination purposes. More particularly, this invention relates to a membrane distillation system with multiple cells in which the system's flux is increased due to the temperature and pressure differential within the system. The configuration of the vacuum air gap membrane distillation system allows for latent heat within the system to be recycled effectively reducing the energy consumption of the system.
