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.
