Preparation of Polymer-polymer composites of PEO:NH4ClO4 + x wt.% Camphor sulphonic acid (CSA) doped polyaniline have been successfully done (x = 0 to 6) by solution casting method. Formation of CSA doped polyaniline and incorporation in the matrix composites is confirmed by FTIR studies. XRD studies also confirm the formation of the composites. Impedance plots have given the enhanced bulk conductivity of the composites than pristine polymer electrolyte, as a function of concentration of CSA doped PANI. Maier's space charge model explains enhancement of dominating ionic conductivity behavior with the addition of dispersed phase polyaniline. The total bulk conductivity peaks to 3.4 × 10–6 Scm–1 at low threshold concentration (3 wt.%) of PANI and then decreases which is explained by percolation threshold model. Wagner's polarization studies confirm the mixed ionic + electronic behavior of composites with the contribution due to electrons/holes as high as 20% to the total conductivity. DTA study gives the variation in the melting temperature of constituents of PEO:NH4ClO4-Polyaniline composite.
