Enhanced permeability and biofouling mitigation of forward osmosis membranes via grafting graphene quantum dots

LEGO® brick-inspired ultra-stable and rapid transport 2D membrane for fast water purification

“…Studies have shown that the improved hydrophilicity of the membrane surface can help to form a hydration layer on the membrane surface to eliminate the direct contact of dye molecules, which in turn reduces membrane contamination. 28,48,49 Accordingly, backwashing after pressure filtration can help remove the dye molecules from the membrane and restore the permeability. In summary, it is feasible to employ the subject–object recognition effect to induce the orderly assembly of fGO nanosheets for the construction of continuous and regular interlaminar channels.…”
