Conductivity and thermal behavior of proton conducting polymer electrolyte based on poly (N-vinyl pyrrolidone)

A proton-conducting polymer electrolyte based on starch and ammonium nitrate (NH 4 NO 3 ) has been prepared through solution casting method. Ionic conductivity for the system was conducted over a wide range of frequency between 50 Hz and 1 MHz and at temperatures between 303 K and 373 K. Impedance analysis shows that sample with 25 wt.% NH 4 NO 3 has a smaller bulk resistance (R b ) compared to that of the pure sample. The amount of NH 4 NO 3 was found to influence the proton conduction; the highest obtainable room temperature conductivity was 2.83×10 −5 S cm −1 , while at 100°C, the conductivity in found to be 2.09×10 −4 S cm −1 . The dielectric analysis demonstrates a non-Debye behavior. Transport parameters of the samples were calculated using the Rice and Roth model and thus shows that the increase in conductivity is due to the increase in the number of mobile ions.

“…The disappearance of high frequency semicircular portion leads to a conclusion that the current carriers are ions and hence the total conductivity is mainly the result of ion conduction. The bulk resistance (R b ) can be retrieved from the intercept of high frequency semi-circle or the low frequency spike on the Z′ -axis [13]. The ionic conductivity values of the electrolytes are calculated by using the equation:…”

A solid-state compact potentiometric hydrogen gas sensor was developed using CH 3 COONH 4 -doped chitosan as polymer electrolyte. The 40 wt% CH 3 COONH 4 -doped chitosan was used as the electrolyte in the sensor. The X-ray diffraction and the scanning electron microscope results showed that the nano-sized platinum working electrode and silver reference electrode were deposited on the respective side of polymer electrolyte by the impregnation-reduction method. The generated electromotive force increased linearly with the logarithm of hydrogen concentration at room temperature. Either insufficient or excessive impregnating time works against the gas sensitivity, and the polymer electrolyte prepared by impregnating 5 min endows the sensor with the best hydrogen-sensitive performance.
