Graphene oxide membranes—partially oxidized, stacked sheets of graphene1—can provide ultrathin, high-flux and energy-efficient membranes for precise ionic and molecular sieving in aqueous solution2,3,4,5,6. These materials have shown potential in a variety of applications, including water desalination and purification7,8,9, gas and ion separation10,11,12,13, biosensors14, proton conductors15, lithium-based batteries16 and super-capacitors17. Unlike the pores of carbon nanotube membranes, which have fixed sizes18,19,20, the pores of graphene oxide membranes—that is, the interlayer spacing between graphene oxide sheets (a sheet is a single flake inside the membrane)—are of variable size
