The Art of Surface Modification of Synthetic Polymeric Membranes

摘要

The development in the area of surfacemodification of polymeric synthetic membranes since 2000is reviewed. Many patents, articles, and reviews have beenwritten on the development in the area of surface modifi-cation of polymeric synthetic membranes subjected to RO,UF, NF, gas separation (GS), and biomedical applications,mainly since 2000, but recently more attention has beengiven to the modification of their surfaces to obtain desira-ble results. In particular, most emphasis has been given toplasma treatment, grafting of polymers on the surface, andmodifying the surfaces by adding SMMs (surface-modify-ing molecules). New additives are synthesized to make the polymeric membrane surfaces either to be more hydro-philic or hydrophobic, aimed at improvement in selectivityand permeability of the membranes for GS, NF, and RO.Improvement in antifouling by surface modification is alsoa popular topic in the membrane industries. In the last 8years, tremendous research efforts have been made on thedevelopment of antifouling membranes.
