Abstract

In this study, nanocomposite polyvinyl chloride-based heterogeneous cation exchange membranes were fabricated by embedding graphite nanoparticles through solution casting technique. The effects of graphite nanoparticle concentrations in the membrane body on the electrochemical properties of blended membranes were investigated. FESEM and SOM images showed uniform distribution of particles and a uniform surface for the fabricated membranes. XRD patterns showed that the crystallinity of membrane enhanced by the increase of graphite nanoparticle dosage. The obtained results imply that increasing the concentration of graphite nanoparticles in the modified membranes has produced a rougher and a more hydrophobic surface. Membrane potential, transport number, selectivity, flux, and water content for the blended membranes were enhanced initially by increase of graphite nanoparticle concentration up to 2 wt% and after that downward trend found. The electrical resistance of the membranes was reduced by the use of graphite nanoparticles obviously.
