Vapor-induced depolarization currents. II. Application

The models of vapor-induced depolarization currents developed in the preceding paper are applied to an experimental investigation of corona-charged polypropylene electrets. The results are shown to be completely consistent with the theoretical predictions, and with the results of thermally stimulated current experiments. The influence of aging at or below room temperature is studied; it is shown that the evolution of the space charge can be easily followed by vapor-induced depolarization-current experiments.
