AI Technical Summary
Traditional biaxially stretched polypropylene films experience reduced charge-discharge efficiency or even breakdown at high temperatures, limiting the application of polymer film capacitors.
By adding nano-ZnO and amino-hyperbranched polysiloxane to a polypropylene film, and using the amino-hyperbranched polysiloxane as a bridging agent, the nano-ZnO and maleic anhydride-grafted polypropylene are blended together to improve the dispersibility and compatibility of nano-ZnO in the polypropylene matrix, thus preparing an NH2-HSiP modified ZnO/PP composite dielectric energy storage film.
It significantly improves the high-temperature dielectric properties of the film, suppresses leakage current, enhances dielectric energy storage performance at high temperatures, and ensures the stability and electrical properties of the film.
