Synergistic modification of BN and TiO 2 on polyethersulfone multilayered dielectrics for enhanced elevated-temperature energy storage performance
Key Points
The research aims to enhance energy storage performance in polyethersulfone dielectrics through strategic modifications of BN and TiO2.
Multilayered dielectrics were constructed using BN and TiO2 fillers in polyethersulfone (PESU) matrices
Electrical tree growth was evaluated to assess dielectric breakdown strength
High-temperature performance was measured under controlled conditions.
Achieved superior high-temperature breakdown strength compared to untreated PESU
Energy storage performance improved significantly due to synergistic interface modifications
Reduced incidence of electrical trees in modified dielectrics.
Abstract
Rational design of PESU/filler interfaces effectively stagnates electrical tree growth, achieving superior high-temperature breakdown strength and energy storage.
