Synergistic Molecular Engineering and Crosslinking Topology for High‐Temperature Energy Storage in All‐Organic Dielectrics
This work presents an all‐organic polymer dielectric that combines high‐energy density with excellent high‐temperature endurance. To address the significant loss in polyetherimide (PEI) at high temperatures, a synergistic strategy is employed. This strategy involves the introduction of trifluoromethyl (CF 3 ) grou...
