Ferroelectrets Filled with a High Breakdown-Strength Gas
2018 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP), 2018Ferroelectrets (i. e. voided, soft polymer composites with internal bipolar space charges) were prepared by laminating porous spacers between polyproplyene films in gas mixtures containing sulfur hexafluoride $(\mathrm{SF}_{6})$ , a gas of higher electric breakdown strength than air. This has the potential to reduce “back discharges”, which occur when

Intrinsic electric strength and electromechanical breakdown in polythene
Proceedings of the Institution of Electrical Engineers, 1965The electric strength of polythene in the absence of surface discharges decreases sharply above room temperature, and there is evidence that this is an electromechanical effect. An optical-lever system, suitable for measuring electromechanical strains in recessed polythene specimens at 80° C, showed that true compressive strains were masked by a much ...
