Effect of cation and salt concentration on conductivity and microstructure characteristics of polyether electrolytes doped with alkali metal perchlorates

Article Abstract:

The conductivity of the set of poly(ethylene glycol) methyl ether (PEGME) based electrolytes doped with alkali metal perchlorates is studied as a function of alkali metal cation and salt concentration. At salt concentrations less than 10(super -2) mol/kg higher conductivities are obtained for Li, Na, and K perchlorates, whereas at salt concentrations greater than 1 mol/kg conductivities measured for Cs and Rb perchlorates are higher.

Electrogenerated chemiluminescence in poly(dibutoxphenylenevinylene) coatings

Article Abstract:

Experiments on Electrochemiluminescence (ECL) are carried out in acetonitrile electrolyte with platinum electrodes coated with poly, DB-PPV. The study concluded that coatings of DB-PPV on platinum electrodes in acetonitrile electrolyte behave as permeable electroactive films with both mobile electronic and ionic charge carriers.
