Dynamically disordered hopping, glass transition, and polymer electrolytes

摘要: The central parameter of the dynamically disordered hopping (DDH) model, renewal time, is correlated with characteristic time constant glass transition relaxation in polymer–salt complexes. With this identification, frequency‐dependent permittivity these materials can be quite adequately described. In particular, experimental evidence for a high‐frequency predicted by DDH model presented. This corresponds to polarization ions their local percolation clusters as they wait event occur. light information on direct current properties complexes are used calculate size clusters. These calculations suggest that motion an ion absence (polymer segmental motion) displacements within its coordination ‘‘cage’’ rather than between several available sites.
