The ion-selective conduction of the PVC/PEO blended membranes was investigated as a function of frequency, temperature and aging time through impedance spectroscopy. It was found that the dielectric behavior of the blended membrane is affected by these physical factors. Analysis of the impedance data showed that the AC conductivity increases with increasing temperature, frequency and aging time. It also was found that the calculated activation energy of the thermoelectrical process decreases with temperature due to enhancement of the ionic conduction in the membrane bulk. However, the enhanced ion-selective conduction suggests the suitability of the prepared blended membranes to be used in the ion selective electrode technology. |
