Tuning d-spacing of graphene oxide nanofiltration membrane for effective dye/salt separation

, 2022
The interlayer spacing (i.e., d-spacing) plays a crucial role in determining the selectivity and permeability of nanofiltration membranes. A high-throughput directional filtration can be achieved by designing and controlling the d-spacing. In this study,
