Polymer film capacitors are widely used in many fields, such as high-pulse power technology, aerospace technology, and new energy vehicles due to their ultra-high charge and discharge efficiency. Polymer dielectrics used in energy storage applications often require high energy density and energy storage efficiency, and biaxial tensile polypropylene (BOPP) films, which are widely used in commercial thin-film capacitors, cannot meet the increasing demand for energy storage. Among many polymer dielectric materials, polymethyl methacrylate (PMMA) has attracted extensive attention due to its high breakdown strength, low dielectric loss, and easy processing. In this paper, the research progress of PMMA basic characteristic and composite dielectric materials in the field of energy storage was reviewed. The methods to improve the energy density and energy storage efficiency of polymer dielectric materials through chemical modification and physical modification were summarized, and the future development direction of dielectric materials was prospected.
