Facile Fabrication of Freestanding Ultrathin Reduced Graphene Oxide Membranes for Water Purification

Freestanding ultrathin rGO membranes, with thicknesses down to 17 nm, are fabricated via a facile approach using hydroiodic acid vapor and water-assisted delamination. These unique membranes provide the potential for addressing the key challenge that limits the performance of current forward osmosis membranes.
