Controllable corrugation of chemically converted graphene sheets in water and potential application for nanofiltration

Abstract

A combination of AFM, SEM and permeation experiments suggests that the amplitude of corrugation of chemically converted graphene (CCG) sheets in water can be readily controlled by hydrothermal treatment, leading to a new class of permeation-tuneable nanofiltration membranes. © 2011 The Royal Society of Chemistry.
