Improved high‐temperature electrical properties of polypropylene insulation material by grafting styrene

open access: yesHigh 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.

Achieving Less Than 100 ppb Total Metal Ion Concentration in ESCAP Resins Synthesized by Atom Transfer Radical Polymerization

open access: yesMacromolecular 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.

PECVD and PEALD on polymer substrates (part II): Understanding and tuning of barrier and membrane properties of thin films

open access: yesPlasma 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 ...
