Description

technical field [0001] The invention relates to the technical field of membrane materials, in particular to a method for preparing a poly-4-methylpentene nanosheet composite film. Background technique [0002] With the rapid development of high-tech industries such as the Internet of Things, big data, new energy vehicles, and smart terminals, the global capacitor market has achieved rapid growth. Capacitors play a vital role in the power grid. In a high-temperature environment, frequent switching and self-heating problems can easily cause the temperature of the capacitor body to be too high, which will cause changes in the internal insulation medium and reduce the insulation level. Even cause damage to the capacitor. With the continuous improvement of integration and assembly density of electronic components, the performance requirements of capacitors are getting higher and higher, and it is imperative to develop capacitors with excellent comprehensive performance.
