摘要：Polymer-based composites filled with ceramic particles such as barium titanate (BT) or lead zirconate titanate (Pb (Zr,Ti)O-3) are considered as ideal materials for energy storage capacitors in electric systems. In this study, we fabricated poly (methylmethacrylate) (PMMA)/poly (vinylidene fluoride) (PVDF) composite films filled with a small amount (10 wt%) of BT by solution casting and investigated their dielectric properties. Our results indicate that the dielectric constants and breakdown strengths of the composites are strongly influenced by the mass content of PMMA. Furthermore, the composite film exhibits excellent energy properties (U-e, similar to 9.145 J cm(-3); eta, similar to 73.84%) when the mass ratio of PVDF and PMMA is 5:5. These composites possess significant potential as high-performance dielectric materials for energy storage capacitors.
