Abstract

Proton conducting solid polymer electrolytes of Poly(ethylene oxide) (PEO) complexed with Tetramethylammonium Chloride (TMACl) have been prepared by means of solution casting process. The complex formation between the polymer PEO and TMACl is evident from the changes in COC, CH stretching and CH2 rocking FTIR vibrational modes. The COC stretching and deformation bandwidth and intensity around 1100 cm–1 is decreased severally with increasing salt content to PEO, and this change in complexed films is due to the interaction between the PEO polymer chain and proton of TMACL molecule. Differential Scanning Calorimetry (DSC) results show that the PEO melting temperature is at 69 °C, which is shifted towards lower temperature with the addition of TMACl salt. From the Wagner’s polarization technique, it is confirmed that the charge transport in these polymer electrolyte films is predominantly due to ions. The conductivity in this PEO:TMACl complexed films are found to be 103 times larger compared to pure PEO.

Keywords: FTIR spectroscopy, solid polymer electrolytes, differential scanning calorimetry (DSC), transport numbers, DC electrical conductivity
