Polyvinylchloride (PVC) based heterogeneous cation exchange membranes were prepared by the solution casting technique. The effect of super activated carbon nanoparticles concentration as filler additive in membrane matrix on ionic transfer behaviors of the membrane was studied. SOM images showed uniform particles distribution and relatively uniform surfaces for the membranes. The membrane water...

Cation exchange membranes are used for electrochemical reduction of CO 2 in alkaline media, where the anion conductivity hydroxide (OH − ) and bicarbonate (HCO 3 essential process. Any partial anionic species containing (i.e. or carbonate (CO 2− ions) causes parasitic transport , a critical issue technology. In this work, cation contacted with support electrolytes is experimentally studied hydr...

With the classical sulfonation method of polystyrene-based strongly acidic cation exchange resins, polystyrene/polyvinylidene fluoride (PVDF) alloy particles were sulfonated to obtain a cation exchange resin, which was then directly thermoformed to prepare a semi-interpenetrating polymer network (semi-IPN) cation exchange membrane. The effects of the swelling agent, sulfonation time and tempera...
