PEMA as a supportive host matrix is physically blended in five different proportions with PVdF-HFP based system containing LiBETI as a electrolyte, EC / DMC mixture in 1:1 v/v ratio as a plasticizer and as a filler for improving ionic conductivity is attempted. The A.C impedance, DSC, and FTIR studies are carried out. The ionic conductivity measurements on these Polymer Blend Nano Composites(PBNC) showed that blending improved ionic conductivity, and enhancement in magnitude is observed for 22.5% PEMA blended PVdF-HFP (7.5 wt%) system with 7.5% . The DSC showed PEMA interaction with PVDF causing reorientation of VDF crystals and resulting conformational changes showed variations in melting endotherms, are observed. FTIR studies identified PEMA interaction with plasticizer and PVdF-HFP through the change in the C-F stretching and C=O Carbonyl bond.
