preparation and characterization of composite anion exchange membrane modified by TIO2

In this research, titanium dioxide (TiO2) /polyvinylchloride (PVC) nano-composite heterogeneous anion exchange membranes were prepared by solution casting technique. The effect of TiO2 nanoparticle concentration on membrane electrochemical properties was studied in NaCl solution. Membrane potential and permselectivity improved with the increase in TiO2 nanoparticles, prepared membranes also showed a remarkable increase in ionic flux and permeability by loading more nanoparticles. Membrane water content decreased by the increase of nanoparticle concentration.
