Enhanced High‐Temperature Capacitive Energy Storage in Topology‐Regulated Semi‐Aromatic Polyimides by Triazine Polarized Nodes and Helical Transport Barriers
Polymer dielectrics operating under extreme environments require increasingly higher demands on electrical insulation performance. Polyimide (PI), one of the most promising candidates for high‐temperature energy‐storage dielectrics, tends to form charge‐transfer complexes (CTCs) under high temperatures and high ele...
