Development of Low-Fouling Polymer Membranes via Photoinitiated Grafting

3 DEVELOPMENT OF LOW-FOULING POLYMER MEMBRANES VIA PHOTOINITIATED GRAFTING [Pg.45]

Currently, UV-initiated graft polymerization has been widely used for the surface modification of polymer manbranes in attempts to develop composite manbranes with enhanced resistance toward organic fouling and biofouling. As can be seen in Table 3.1, different hydrophilic monomers, such as Af-vinyl-2-pyrrolidone (NVP), A-vinylformamide (NVF), A-vinyl-caprolactam (NVC), 2-hydroxyethyl methacrylate (HEMA), acrylic acid (AA), acrylamide (AAm), 2-acrylamidoglycolic acid (AAG), [Pg.45]

Surface Modification of Polymer Membranes via UV-lnitiated Grafting to Reduce Their Fouling [Pg.45]

UF of BSA solutions modified membranes, especially with NVP, showed higher flux and lower fouling compared with the unmodified membrane (Pieracci et al. 1999) [Pg.45]

UF of sugarcane juice and BSA solutions modified membranes showed more resistance to fouling and a higher rejection than unmodified membranes relatively high monomer concentration (40 g/1) at medium irradiation times (1.5-3 min) were among the optimal modification conditions to reduce membrane fouling (Susanto et al. 2007) [Pg.45]
