preparation and electrochemical charaterization of anion exchange membrane modified by polyvinylpyrrolidone

In this research AEMs were prepared through solution casting technique. To modify electrochemical properties of membranes, polyvinylpyrrolidone (PVP) was added to the solution. Result revealed that membrane water content increased by increasing PVP. Membrane potential and permselectivity initially showed an increasing trend then a decrease. Ionic permeability and flux of prepared membranes decreased by increasing PVP loading in solution and IEC showed an increasing trend
