Conductivity relaxation in Ag+ ion conducting PEO-PMMA-PEG polymer blends

In this paper, the electrical conductivity and relaxation studies in two different temperature regions (T < T (m) and T > T (m)) on plasticized PEO-PMMA blend polymer electrolyte system with AgNO3 salt are reported. The polymer electrolyte system has been prepared by solution cast technique and characterized by X-ray diffraction and differential scanning calorimetry. The conduction and relaxation processes at various temperatures have been investigated in the framework of modulus formalism. The distribution of relaxation times is discussed using Argand plot. Variation in ionic conductivity of polymer blends is discussed with the increase of PEO as well as with temperature.
