The results of an experimental investigation on the charge formation and decay characteristics of SR 10 vinyl (PVC) electrets prepared at different temperatures are presented in this paper. The results show that the polarity of the final charge on either side of the electrets is positive irrespective of the polarizing conditions. It is also shown that polarizing temperature has a major influence on the behavior of vinyl electrets.
