On the role of driving force in water transport through nanochannels within graphene oxide laminates

Abstract

The comprehensive understanding of water transport in GO membranes is of great interest. The water transport mechanism studied by many researchers suggests that capillary pressure is the driving force of water transport in GO membranes at the highest humidity level. Besides the capillary pressure, low-friction flow and surface diffusion also contribute to the fast water transport. This mini review provides an integrated image on the role of driving force in water transport through nanochannels in GO membranes which can be helpful in developing high-performance GO-based membranes in future for water, environment and energy-related applications.
