چکیده:
In this research, heterogeneous cation exchange membranes were prepared by casting-solution techniques using polycarbonate (PC) and S-polyvinylchloride (S-PVC) as binders and cation exchange resin. The effect of polymers blend ratio on structure and electrochemical properties of the prepared membranes were elucidated. The microstructures of the membranes were investigated by scanning electron microscopy (SEM). Ion exchange capacity (IEC) and water content were studied. The mechanical strength test was performed for investigation of membranes mechanical properties. The measurements indicate that the water content of membranes is enhanced by increasing the PC ratio in the casting solution. The SEM images show that addition of PC ratio in the casting solution or blending with S-PVC result in a membrane with more inner cavities and micro voids. The results reveals that ion exchange capacity of SPVC/ PC blend membranes is increased compared to S-PVC and PC based membranes. Furthermore it was found that blending S-PVC and PC polymers results in membranes with lower mechanical strength.
