Molecular Dynamics and Charge Transport in highly-conductive Polymeric Ionic Liquids
Glassy dynamics and charge transport are studied for the polymeric ionic liquid (PIL) poly[tris(2-(2-methoxyethoxy)ethyl)ammonium acryloxypropyl sulfonate] (PAAPS) with varying molecular weight (9700, 44200, 51600, and 99500 g/mol) by broadband dielectric spectroscopy (BDS) in a wide frequency (10−2−107 Hz) and temperature range (100−400 K) and by DSC- and AC-chip calorimetry.
The dielectric spectra are characterized by a superposition of (i) relaxation processes, (ii) charge transport, and (iii) electrode polarization. Continue reading “Talk by F. Frenzel at UL (October 24, 2017)”
