Solvent effects on the charge storage ability in polypyrrole

Solvent effect on the charge storage ability of the polypyrrole have been s tudied in two different ways:analyzing both the ion-solvent and polymer-sol vent interactions and by a multiple regression procedure. The first way was not sufficient to explain all the results obtained. By the multiple regres sion, influence of the four different Variables of the solvents simultaneou sly has been obtained. Solvents having high dipole moments and low polariza bility and having a high capacity to donate electrons are the best solvents among those investigated in this paper to obtain high charge storage abili ties.
