Windowing polarization: considerations for the study of the space charge relaxation in poly(methyl methacrylate) by thermally stimulated depolarization currents

摘要

The windowing polarization technique is an electret formation method which has been widely used to study the structure of polar relaxations in polymers. In this paper we have studied the effect of some polarization parameters to extend the applicability of this method to the explanation of space charge relaxation in poly(methyl methacrylate).
