Dielectric and AC Conductivity Studies of NaCF3SO3 -PEO Doped Polyaniline Complexes

The polymer electrolyte based on polyethylene oxide (PEO) complexes with conducting Polyaniline (PANI) and Sodium triflate salt (NaCF3SO3) has been prepared in different weight percentage (wt %) by in-situ polymerization method. The complexation is confirmed by Fourier transform infrared spectroscopy (FTIR) studies on PANINaCF3SO3PEO complexes, and the peak at 1122 cm-1 is considered to be measure of the degree of electron delocalization, 1487 cm-1 is due to C=C stretching of benzonoid ring, 1558 cm-1 is C=N quinonoid stretching mode of vibration. The ac conductivity has been studied in the frequency range of 50 Hz to 1 MHz and it is found that 30 wt % shows high conductivity compared to pure polyaniline and other complexes.
