Reduced graphene oxide (rGO) has a huge potential for membrane applications owing to its appropriate interlayer spacing (0.34-0.37 nm), which enables it to block salt ions as small as Na⁺ with high precision. However, fabrication of uniform rGO membranes is a great challenge because of the loss of its polar functional groups during preparation from graphene oxide (GO). This work utilizes the facile approach of synthesizing reduced GO by environmentally viable hydro-thermal reduction. The key factors and functional groups that govern membrane formation were investigated. Further, water transport behaviour of rGO membranes was discussed.
