Overcoming polarization-breakdown trade-off via hydrogen bonding-modulated molecular stacking in high-temperature high-energy-density flexible dielectric

Flexible dielectrics suffer from an inherent polarization-breakdown trade-off. Herein, we propose a hydrogen bonding-modulated molecular stacking strategy to improve high-temperature capacitive energy storage performance. A series of polyetherimide copolymers with tunable hydroge...
