In this paper, the effect of all anionic (polyvinyl pyridine iodide, AM-1) and cationic (polystyrene sulfonate sodium. CM-1) exchange polymer layer on the chronopotentiometry (CP) and current voltage Curves (I-V) of a charged composite membrane are investigated. Also, the ion transport near the interface between electrolyte and ionic exchange polymer membranes (anionic and cationic ones) and a charged mosaic polymer composite membrane is studied. The results show that both anionic and cationic polymer exchange membranes exhibit a lower voltage drop over the range of applied current density and possess favorable industrial application potentials, especially at a low KCl concentration. While the charged mosaic polymer composite membrane did not show any current-voltage change, irrespective of the type and the concentration of used electrolyte. CP and I-V measurements are effectively used to give some fundamental understanding for ion transport behavior of an Ion exchange polymer membrane near the interface.
