Atomically thin membranes from 2D materials offer unique opportunities for molecular separations with high
permeance and high selectivity. Here, we report the fabrication of fully functional centimeter scale nanoporous
(<2-3nm) atomically thin graphene membranes for molecular separation applications. Our work focuses on
systematically addressing key challenges that have limited progress in field i.e. a) scalable nanopore
formation methods including in-situ approaches, b) facile support casting, c) novel defect sealing methods and
d) scalable manufacturing approaches. The synthesized nanoporous atomically thin membranes show higher
selectivity and permeance (up to 100 times more) than state-of-the-art polymeric membranes and can be
readily used for lab-scale dialysis.
