摘要
Described herein is a graphene oxide and polymer based selectively permeable element that provides selective gas, and vapor resistance for dehumidification applications. The graphene oxide is cross- linked with polyvinyl alcohol, the polymer comprises an ammonium salt polymer such as poly(diallyldimethylammonium) chloride. Also described is a selectively permeable element where the graphene may be selected from reduced graphene oxide, graphene oxide, and is also functionalized or crosslinked. Also described is a selectively permeable element where there is crosslinking between the graphene and/or the polymers to provide enhanced gas resistance with water vapor permeability. A selectively permeable device is also described that incorporates the selectively permeable element and further comprises a substrate and a protective coating, encompassing the selectively permeable element. Also described are methods for making the aforementioned selectively permeable elements and related devices.
