title: Unconventional scaling of electrical conductivity spectra for PSS-PDADMAC polyelectrolyte complexes.
abstract: For the first time, we analyze ac conductivity spectra of various dried ionically cross-linked polyelectrolyte complexes in terms of the time-temperature superposition principle. The temperature-dependent spectra of some complexes show scaling properties that are distinctly different from the behavior of all other ion-conducting materials reported so far, but in agreement with model predictions by Roling [B. Roling, Phys. Chem. Chem. Phys. 3, 5093 (2001).10.1039/b105094j]. We conclude that the dc conductivity of the investigated PEC is always governed by the Na+ ions, even in complexes with excess of polycations and chloride anions.
