Remarkable dielectric breakdown strength enhancement of a PVDF terpolymer using a 2D hybrid organic inorganic perovskite as a functional additive

Abstract

A two-dimensional hybrid perovskite, (PEA)2PbI4, is added as a functional additive to a dielectric PVDF terpolymer matrix to improve its dielectric strength. It is found that a trace amount of added (PEA)2PbI4 of 0.1 wt% gives rise to a 25% improvement in the DC dielectric breakdown strength of the polymer. Mechanistic study using terahertz time-domain spectroscopy reveals that the perovskite additive reduces the carrier density in the polymer matrix correspondingly, which is believed to be the main reason that leads to a large breakdown strength enhancement. This work presents not only a novel potential application of a 2D hybrid perovskite, but also a practical approach to modify polymeric dielectric materials for the achievement of excellent electrical insulating performance.
