Ultrafast water evaporation through graphene membranes with subnanometer pores for desalination

Controlling the pore sizes of graphene-based membranes is essential for exploring their transport properties and related applications such as water desalination. We demonstrated the scalable fabrication of ultrathin graphene membranes with precisely controlled subnanometer pores by co-assembly of graphene oxide nanosheet and polymer on a porous ceramic substrate and subsequent reduction and carbonization. The resulting graphene membranes with an...
