    Abstract: A coating process is described that coats a coil-to-coil continuous substrate with a graphene-like coating. The coating process includes cleaning and activating a substrate, applying a graphene oxide dispersion to the substrate, drying the coated sub-strate, and exposing the dried coating to VUV radiation under a dry atmosphere. The atmosphere for the last step includes one or more inert gases and optionally one or more reactive gases to repair defects in the coating and/or to functionalize the coating. This coating process allows for the formation of a polygranular graphene-like coating intimately in contact with the substrate. The graphene-like coating coats the substrate with multiple monolayers of graphene in a continuous manner.

    Abstract: The present invention provides a multi-stage filter system suitable for the production of drinking water from a wide variety of contaminated water sources. The modular nature of the multi-stage filter system allows for the customization of filter combinations according to the remediation requirements. The multi-stage filter system comprises a coarse filter (S1); an ultrafiltration filter (S2); a graphene-based filter (S3); and a residual nanoparticle filter (S4). The graphene-based filter cartridge comprises few-layer graphene powder; a combination of few-layer graphene powder and pellets comprising a mixture of polyethersulfone, graphene oxide (GO), and dimethylformamide; a composite comprising chitosan, GO, sodium sulfate and ferric chloride; or a combination of few-layer graphene powder, granular activated carbon and a composite comprising chitosan, GO, sodium sulfate and ferric chloride.
