Aging-resistant breakdown performance of polypropylene nanodielectrics.

The current work discusses the effects of vacuum and oxidative aging at 110°C on the direct current breakdown performance of pure polypropylene (PP) and PP nanodielectrics having 1 wt%, 2 wt%, and 5 wt% of magnesium aluminate, calcium carbonate, and surface-treated calcium carbonate nanoparticles.
