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
