Recent Research Improvements in Ternary Polypropylene Dielectric Materials
The accelerated development of energy market requires higher voltage level,larger capacity as well as smaller size of power equipment,in consequence,the PP-based material is required to possess the enhanced electrical,mechanical and thermal properties,and to maintain the processibility,environmental friendless,economic efficiency and so on.Ex-tensive works have been carried out and excellent results have been achieved on the improvement of a certain property of PP;however,how to simultaneously enhance multiple properties is still the challenge in recent years.Among the re-searches,the ternary PP composite that both introduces the polymer blends and nanocomposite presents promising results.In this paper,recent research achievements in"PP/Polymer/nano particles"ternary PP composites were summarized.Based on the results,the mechanism of collaborative improvements of insulating and mechanical properties was revealed,and the model of balanced tailoring of energy storage density and dielectric loss was established.Finally,the prospects of future studies on ternary PP composites were proposed.
