ABSTRACT Biaxially oriented polypropylene (BOPP), the dielectric material of choice for polymer film capacitors, is widely used in advanced electronic devices and power grids, among other applications. However, nonlinear growth conduction loss at high temperatures leads to a rapid deterioration its energy storage performance, which seriously hinders development trend miniaturisation integration systems. In this study, inorganic nanolayers with heterogeneous structure were grown on surface BOPP films by magnetron sputtering using constant BaZrTiO 3 wide bandgap Al 2 O ceramic targets. Experimental theoretical analyses show that use as heterojunction outer layer can effectively impede carrier injection transport, leading significant reduction leakage current density composite film, enhancing temperature performance films. The synergistic enhancement properties insulating strength attributed ability /BaZrTiO /BOPP/BaZrTiO /Al (O‐B‐P‐B‐O) exhibit discharge 2.49 J/cm charge/discharge efficiency 77.6% 125°C 500 MV/m.
