"interfacial layer given more uniform/ optimized nano-channels, stopping restacking/ misalignment creating dead ends for water molecules... smoothed interface glides water through atomic-scale gaps with significantly less friction... membrane still filters out >99% salt ion/ organic contaminants... reinforces membrane's mechanical bond preventing swelling/ degrading with long water submersion, graphene oxide much cheaper than graphene, less pressure/ electricity in desalination/ purification plants"
