Abstract
Dynamics of corona poling of three layer FEP/ ePTFE/FEP sandwiches was analyzed theoretically. Thereby the temporal behavior of the involved electric fields, potentials and charges were obtained and compared to experimental data. From those results the optimal poling voltage providing the highest accumulated areal charge density at the FEP/ePTFE interfaces as well as the optimized sample geometry were derived. The thermal stability and relaxation processes during thermally stimulated open-circuit current measurements for poling at 25 °C and 150 °C were studied.
