Electrode poling of cellular polypropylene films with short high-voltage pulses
(Conference on Electrical Insulation and Dielectric Phenomena (CEIDP), Annual Report, 2002-01-01) [Trabalho apresentado em evento]
Recently, piezoelectric cellular polypropylene (PP) was proposed as a new type of quasi-ferroelectric. The observed hysteresis of the charge density as a function of the electric field could be explained as field-dependent ...
