Understanding the role of graphene oxide dispersion on tuning membrane properties for water nanofiltration

Graphene-based membranes have shown great potential for water filtration due to the unique and tunable laminar structure of graphene materials. In this study, the properties of graphene oxide (GO) membranes were tuned in a simple and scalable manner by adjusting the formation conditions, particularl...
