Abstract

The charge storage stability of poly(ethylene/tetrafluoroethylene)(ETFE) electrets after constant voltage corona charging was studied.The comparison of the charge stability of ETFE and that of several important electret materials was investigated.It is found that the charge stability of ETFE electret is very good,and the stability of negatively charged ETFE is much better than that of positively charged ETFE.The charge storage lifetime can be obviously improved after heating treatment.The activation energy of positive-and negative-charged ETFE electrets was estimated,and at the same time,the characteristic of the transport of detrapped charges for ETFE electret was discussed.
