Enhanced High-Temperature Capacitive Performance of a Bilayer-Structured Composite Film Employing a Charge Blocking Layer

Abstract: The great development potential of polymer dielectric capacitors in harsh environments urgently requires enhancing capacitive performance at high temperatures. However, the exponentially increased conduction loss at high temperature and high field results in a drastic drop in energy density and charge–discharge efficiency. Here, a bilayer-structured polyimide (PI) composite film containing a wide-band gap inorganic layer as a charge blocking layer is designed. The inorganic layer improves the charge trapping a… Show more

“…Based on organic/inorganic composites, the lower defect content favors the stability, and the excellent stability performance of 0.2 wt% BFO@AO/CRC films confirmed its outstanding compatibility between the filler with the polymer, as shown in Fig. 4d 7,37–43 A considerable power density and ideal charge/discharge rates allow electrostatic capacitors to be used in electromagnetic artillery, high-voltage cables, and other applications. Fast charge–discharge tests of CRC and its nanocomposites were performed at 180 MV m −1 DC voltage, as shown in Fig.…”

“…It should be noted that the copolymer films are only synthesized using conventional commercial monomers. Compared with the other high temperature polymers by using external components, such as making nanocomposites or multi-layer structures, [5,15,17,23,41,43,53,[57][58][59][60][61][62][63][64][65][66] the flexible copolymer film is compatible with the industrial production line of current commercial polymer films and has the potential to be applied in hightemperature environments of electric vehicles, power electronics, and other systems.…”

“…Polymer film capacitors, as one of the core components in modern electronic devices and electronic circuits, possess excellent characteristics such as low loss, self-healing, and microsecond-level charge/discharge rates. Large-scale applications in various fields (e.g., healthcare security, transportation, national defense) are placing higher demands on the new generation of dielectric capacitors, i.e., requiring dielectric polymers capable of operating stably in coordination with high electric fields and high temperatures. For example, in the aviation and aerospace fields, electronic component devices need to be placed near engines (200–300 °C). High-temperature operating environments would lead to many electronic devices equipping with additional cooling devices .…”
