Abstract:

Currently, the biaxially oriented polypropylene (BOPP) is primarily employed as a core material by commercially available thin film capacitors. Although BOPP is the most commonly used polymer film for thin film capacitors, it still presents challenges in low energy density and limited operating temperature range. This paper presents a comprehensive review in the recent advancements in utilizing BOPP films for capacitors, focusing on the studies on enhancing the dielectric and energy storage properties of dielectric materials. The new insights provided by this paper can serve as a valuable reference for the future research and development of high⁃performance polymer⁃based dielectric materials. This paper also offers prospect for the potential research direction in future.

Key words: biaxial polypropylene, capacitive, film, energy storage, dielectric
