Currently, conventional polypropylene films encounter performance bottlenecks, such as poor dielectric properties and insufficient heat resistance, in devices such as high-voltage DC transmission converters, DC/DC converters for electric vehicles, and pulsed power supplies, which constrain their application in a number of critical areas. These issues have driven scientists and engineers to search for new methods and technologies to improve the performance of polypropylene films (Du et al. in IEEE Trans. Dielectr. Electr.

These issues have driven scientists and engineers to search for new methods and technologies to improve the performance of polypropylene films (Du et al. in IEEE Trans. Dielectr. Electr.
