Segmental‐Incompatibility‐Enabled Non‐Conjugated Nanodomains for Aggregation‐State Regulation of Wide‐Temperature Polyimide Energy‐Storage Dielectrics
Addressing the issues of accelerated charge migration and diminished energy storage performance in polyimide (PI) under a high‐temperature electric field, this study proposes an aggregation‐state regulation strategy through the construction of non‐conjugated nanodomains in PI‐based copolymers. By introducing non‐co...
