Molecular dynamics and charge transport in polyisobutylene-based ionic liquids — •Falk Frenzel¹, Makafui Yao Folikumah², Matthias Schulz², Wolfgang Binder², and Friedrich Kremer¹ — ¹Institute of Experimental Physics I, University of Leipzig, Linnéstr. 5, 04103 Leipzig, Germany — ²Institute of Chemistry, Martin-Luther-University Halle-Wittenberg, Von-Danckelmann-Platz 4, 06120 Halle (Saale), Germany

Broadband dielectric spectroscopy (BDS) and differential scanning calorimetry (DSC) are employed to study molecular dynamics and charge transport in polyisobutylene(PIB)-based ionic liquids. The latter form a homologous series of polymeric 'Ionic Liquids' containing monovalent and bivalent telechelic PIBs either with N,N,N-triethylammonium as the functional group or 1-methylpyrrilidinium. Three well separated dielectric relaxation processes and a conductivity contribution are obtained. This offers to unravel the interplay between molecular dynamics and charge transport in this novel class of materials.
