Melt Grafting of Geometry‐Tailored Voltage Stabilizers for High‐Performance Polypropylene Insulation
Advanced Functional Materials, Volume 36, Issue 30, 13 April 2026.A scalable one‐step melt grafting strategy is developed to enhance the dielectric properties of isotactic polypropylene by covalently incorporating thermally stable aromatic voltage stabilizers. This solvent‐free approach improves volume resistivity and DC breakdown strength through deep trap formation and charge localization, offering a sustainable ...

trans-Ethylenedi-p-phenylene diacetate
, 2009 The centrosymmetric title compound, C18H26O4, was prepared in high yield from 4-acetoxystyrene via Ru-catalysed homo-olefin metathesis. Exclusive formation of the E-configurated isomer was observed.

High Voltage, Volume 10, Issue 3, Page 603-614, June 2025.Abstract The electrical properties of polypropylene (PP) insulation material decrease dramatically at high temperature, which limits its application in harsh environments. This study investigates how grafting styrene (St) improves the high‐temperature electrical properties of PP.

Macromolecular Materials and Engineering, Volume 309, Issue 4, April 2024.The environmentally stable chemical amplified photoresist resin is synthesized via atom transfer radical polymerization achieving polydispersity index as low as 1.25. It is then purified by ion exchange with two different resins, IRC747 and A15, which are effective at removing Cu and other metal ions.

Plasma Processes and Polymers, Volume 21, Issue 3, March 2024.Recent results on the analysis of plasma/polymer interactions and the nucleation of ultrathin plasma films by plasma‐enhanced chemical vapor deposition and plasma‐enhanced atomic layer deposition on polymeric substrates are shown. The adjustment of deposition parameters and substrate selection leads to either effective diffusion barriers or films with ...
