An environmental-friendly electrostatically driven method for preparing graphene oxide composite membranes with amazing stability in aqueous solutions

Graphene oxide (GO) membranes are outstanding candidates for desalination and wastewater treatment thanks to the fast water permeation through two-dimensional nanocapillaries, combined with size and electrostatic ion exclusion mechanisms. However, their use for ionic and molecular separations is limited due to swelling phenomena which reduce both, selectivity and mechanical stability of GO laminates.
