- Abstract
Elevated temperatures significantly contribute to the deterioration of electrical performance in polymeric insulation under HVDC conditions. To enhance the power transmission capacity, it’s crucial for new cable designs to incorporate insulation materials with superior high-temperature resistance, involving heightened breakdown strength, minimized space charge accumulation, and reduced conductivity. In this study, a small quantity (~1.0 phr) of Octa-aminophenyl POSS (OaPOSS), a type of supernano, is blended into polypropylene (PP) to create OaPOSS/PP nanocomposites with upgraded electrical properties. Through thermally stimulated depolarization current (TSDC) analysis, it was clear that the incorporation of OaPOSS enhanced both the trap level and the density of deep traps within the PP matrix. The functionality of OaPOSS is elucidated by examining both the interface between OaPOSS and pristine PP, and the role of the phenyl group in isolated OaPOSS particles. Ultimately, the introduction of OaPOSS presents a novel approach to adjusting the electrical characteristics of pure PP, paving the way for the design of non-cross-linked, eco-friendly thermoplastic insulation materials tailored for HVDC cable applications with exceptional electrical performance.
