Preparation of antifouling PAA pore-filled PVDF membrane coated with TiO2 nanoparticles

An increase in membrane hydrophilicity appears to be an acceptable way to reduce membrane fouling. Titanium dioxide (TiO2) was extensively utilizedto improve the permeability and antifouling property of membranes due to photo-catalytic and super-hydrophilicity effects. In this work, the supportPVDF membrane was modified by pore-filling of poly acrylic acid (PAA) and self-assembling of TiO2. The modified membranes exhibited high flux recovery ratiotowards the nascent membrane due to increasing hydrophilicity
