Claim Text:
1. Antifouling membranes for use in water treatment and materials separation, the membranes having integrating fillers with visible light photocatalytic activity comprising nitrogen—doped TiO 2 nanoparticles used to produce Poly(vinyledene fluoride) PVDF/N—TiO 2 mixed matrix hollow fiber membranes (HFMs) which are activated by visible light, the membranes exhibiting an enhanced surface hydrophilicity compared to a PVDF membrane, and with the fillers also affecting a surface cleaning through a photodegradation process resulting from visible light irradiation so to enhance the fouling resistance of the membranes to organic materials and biomaterials compared to a PVDF membrane.
