Query: 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
acryloxypropylsulfonate) (PAAPS) with varying molecular weight (9700, 44200,
51600 and 99500 g per mol) by Broadband Dielectric Spectroscopy (BDS) in a wide
frequency (0.01 - 10E7 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. The relaxation processes (i) are assigned to the
dynamic glass transition and a secondary relaxation. Charge transport (ii) can
be described by the random free-energy barrier model as worked out by Dyre et
al.; the Barton-Namikawa-Nakajima (BNN) relationship is well fulfilled over
more than 8 decades. Electrode polarization (iii) follows the characteristics
as analyzed by Serghei et al.; with deviations on the low frequency side. The
proportionality between the relaxation rate of the dynamic glass transition and
the charge carrier hopping rate reflects the nature of charge transport as
glass transition assisted hopping. Hereby, the PIL under study exposes the
highest dc-conductivity values observed for this class of materials below 100
oC so far, and for the first time a conductivity increase by rising degree of
polymerization. The comparison of the polymeric Ionic Liquids under study with
others implies conclusions on the design of novel highly conductive PILs.
