Table 1: Ionic conductivity values of MXene doped polymer electrolyte systems calculated at ambient temperature
Electrochemical impedance spectroscopy (EIS) was used to characterize the electrical behavior of various electrolyte layers. In contrast to pure polymer polyethylene oxide (PEO) and polymer salt complex PEO: NaI and films with varying quantities of nanofiller. To insight role of nanofiller in the polymer we have chosen PEO: NaI as host. It has to be acclaimed that PEO has a conductivity of around 1.30 x 10-8 S/cm in the absence of salt. The maximal electronic conductivity was 1.05 x 10-7 S/cm after adding 12 wt% of NaI. Further, addition of nanofiller (MXene)conductivity increases and conductivity maxima obtained at 0.04 wt% of dispersoid with σ value of 2.05 x 10-4 S/cm. Nyquist value of one typical sample is shown in fig. (1) and using equation 1 we have evaluated the σ values and listed in Table 1
