A model of charge transport and electromechanical transduction in ionic liquid-swollen Nafion membranes
چکیده انگلیسی
This paper examines the mechanisms of electromechanical transduction in ionic liquid-swollen transducers based on Nafion polymer membranes. Specifically, the morphology and relevant ion associations within these membranes are investigated by the use of small-angle X-ray scattering (SAXS), Fourier transform infrared (FTIR) spectroscopy, and nuclear magnetic resonance (NMR) spectroscopy. These results reveal that the ionic liquid interacts with the membrane in much the same way that water does, and that the counterions of the Nafion polymer are the primary charge carriers in the ionic liquid-swollen films. The results of these analyses are compared to the macroscopic transduction behavior in order to develop a molecular/morphological model of the charge transport mechanism responsible for electromechanical coupling in these membranes.
