高压直流电缆绝缘用聚丙烯及其纳米复合材料的研究进展
Research Achievements in Polypropylene and Polypropylene/Inorganic Nanocomposites for HVDC Cable Insulation
摘要
Abstract
Due to its excellent electrical and thermal performances,as well as satisfying the needs of developing the environmentally friendly and recyclable cable insulation material,polypropylene has caused widespread concern.Nano-doping can effectively improve the electrical,thermal and mechanical properties of polypropylene nanocomposites,which provides a new method to solve the problems in its application in HVDC cable insulation.We introduce research achievements in polypropylene and polypropylene/inorganic nanocomposites,and present the effects of nano-doping on the electrical properties(such as space charge behaviors,electrical tree ageing,breakdown strength,etc.),thermal conductivity,and mechanical properties of the polypropylene and its multi-blends.The ageing mechanism under different conditions is also discussed.The analysis shows that the surface treatment of nanoparticles can reduce the aggregation of nanoparticles and strengthen the interface effect,thus improving the comprehensive properties of polypropylene nanocomposites.We also summarize the feasibility and future development of the polypropylene and its nanocomposites application in the insulation of HVDC cables.关键词
