Molecular Structure Design of Heat-Resistant Cycloolefin Polymer Based on Machine Learning

Abstract Traditional biaxially oriented polypropylene (BOPP) is widely used in capacitors of converter valves, but its high-temperature performance is gradually approaching its design limit. Cycloolefin copolymer/polymer (COC/COP) materials are explored as promising alternatives...

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...
