Abstract:

Solid polymer electrolytes (SPEs) with poly (vinyl) chloride (PVC) doped with a fixed amount of ammonium trifluoro methane sulfonate (NH₄Tf) and with varying concentrations of ionic liquid butyltrimethyl ammonium bis (trifluoromethyl sulfonyl) imide (Bu₃MeNTf₂N) were synthesised via solution cast technique. PVC-NH₄Tf-Bu₃MeNTf₂N-based SPEs with 15 weight % Bu₃MeNTf₂N exhibit conductivity of 1.56 x 10^-4 Scm^-1 at room temperature. The ionic conductivity is attributed to the dissociation of NH₄Tf facilitated by Bu₃MeNTf₂N. Results of XRD indicate that the most amorphous film has the highest conductivity and this is corroborated by the results of DSC. FTIR spectra revealed that Bu₃MeNTf₂N has weak interaction suggesting that it acts mainly as a lubricant to facilitate polymer segmental motion.
