Charge Transport and Glassy Dynamics in Polymeric Ionic Liquids as studied in its in Inter- and Intramolecular Interactions — •Falk Frenzel¹, Pia Borchert², Arthur Markus Anton¹, Veronica Strehmel², and Friedrich Kremer¹ — ¹Universität Leipzig, Leipzig, Germany — ²Hochschule Niederrhein, Krefeld, Germany

Polymeric Ionic Liquids (PILs) are a novel class of materials in which the properties of Ionic Liquids (ILs) are combined with them of polymeric systems. In the present study Broadband Dielectric Spectroscopy (BDS), Fourier Transform Infrared Spectroscopy (FTIR), AC-Chip Calorimetry (ACC) and Differential Scanning Calorimetry (DSC) are employed to analyze the impact of inter- and intramolecular interactions on charge transport and glassy dynamics. By comparing PILs with their low molecular weight counterparts as well as by systematically varying the anion or cation enables one to unravel the mechanism of charge transport and its interplay with glassy dynamics. The detailed findings are in accordance with the model of a dynamic glass transition assisted hopping conduction.
