Preparation and characterization of cation-exchange membranes based on polycarbonate (PC) & acrylonitrile butadiene styrene (ABS) modified by NiFe2O4 nanoparticles

In this research, polycarbonate (PC) and acrylonitrile butadiene styrene (ABS) based heterogeneous cationexchange membranes modified by NiFe2O4 (Nickel Ferrite) nanoparticles were prepared by casting-solution techniques,and their morphological and electrochemical properties were studied.Ion exchange capacity, transport number,permselectivity and ionic flux were investigated.The results show that in membranes prepared with differentpercentages of nanoparticles, the ion exchange capacity and ionic flux increased toward the membranes withoutnanoparticles. By adding nanoparticles of nickel ferrite, due to the magnetic properties and absorption of thesenanoparticles, and their accumulation around the resin, access to the functional group is reduced and the ion exchangecapacity decreases and with the improvement of the path of the transfer channels increased of the flux.
