Improving the High-Temperature Mechanical Properties and DC Electrical Properties of Polypropylene Insulation Materials through Grafting and Cross-Linking Modification

Thermoplastic polypropylene (PP) has been widely regarded as a promising alternative to cross-linked polyethylene (XLPE) for cable insulation owing to its excellent recyclability. However, PP exhibits poor mechanical toughness at room temperature, and blending with low-modulus elastomers, although effective for tough...

Optimizing the High-Temperature Energy Storage Performance of Polyimide Films Using Double-Layer Interfacial Barrier Layers

Advanced electronic and electrical systems increasingly require polymer dielectric materials capable of delivering efficient energy storage even when subjected to elevated temperatures and intense electric fields. However, conventional polyimide (PI) films suffer from limited energy density and severe performance deg...

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...
