DURABLE GRAPHENE OXIDE MEMBRANES COMPRISING FUNCTIONALIZED SUPPORT COMPONENTS

Abstract: filtration apparatus including graphene oxide (go) membranes are described herein. the go membranes exhibit durability under harsh operation conditions including elevated temperatures, high pressure, and/or non-neutral ph. the filtration apparatus can include a go membrane and a functionalized support including surface functional groups grafted to the functionalized support via a free radical co-polymerization approach. the filtration apparatus can exhibit improved performance (e.g., high rejection) in applications such as pulp and paper processing, which facilitates achieving permeate quality targets. the filtration apparatus described herein can also offer a more stable replacement for reverse osmosis membranes which are known to degrade under strongly alkaline conditions and high temperatures.
