Cross-linked divinylbenzene (DVB) based bi-functional copolymer (BFC) was synthesized using acrylic acid and 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) by free radical copolymerisation reaction. Simple solution casting technique was used to fabricate the bi-functional cation-exchange membranes using polyvinyl alcohol (PVA) as plasticizer. To deliberate the structural and morphological analyses and asses the density of functional groups, state of water, and conductivity of developed membranes, physicochemical characterizations were carried out. Well optimized PVA/BFC-70 membrane showed high bound water content (3.60%) with high membrane conductivity (3.67 x 10(-2) S cm(-1)) and ion-exchange capacity (1.30 mequiv g(-1)). The reported CEM, especially PVA/BFC-70, was assessed for the electrochemical applications. (C) 2015 Elsevier B.V. All rights reserved.
