On negatively corona-charged PTFE film, we have measured the isothermal decay of surface potential with different initial voltages at high temperature. At 150°C, a remarkable corssover effect in the decay curves is found. Prom the TSD current spectra, we find the higher the initial voltage, the wider the current peak broadened to low-temperature side. According to a simple mathematical model, the...
Triboelectricity, which is a kind of old and well known phenomena, has been used as a method of charging of polymer electrets(1). G.M. Sessler has shown that this method has not been used extensively, mostly because of lack of accurate reproducibility(2) R. Gerhard-Multhaupt mentioned in his recent paper that triboelectricity will probably be used as a simple and safe charging method(3). We used "The...
