The electrical performance of Nafion was investigated from -155 to 155°C in the frequency range from 10 mHz to 10 MHz and for two different hydration conditions. The electrical responses are mainly due to conductivity, electrode polarization and relaxation phenomena. These features were correlated to the molecular and nano-scale structure of the material and to the transition/relaxation phenomena observed in both DSC and DMA studies.

Abstract
The electrical performance of Nafion was investigated from -155 to 155°C in the frequency range from 10 mHz to 10 MHz and for two different hydration conditions. The electrical responses are mainly due to conductivity, electrode polarization and relaxation phenomena. These features were correlated to the molecular and nano-scale structure of the material and to the transition/relaxation phenomena observed in both DSC and DMA studies.File in questo prodotto:
