Abstract

The invention discloses a method for preparing a nanocomposite dielectric film. The method comprises the following steps of: firstly obtaining a polymer dielectric film by a Langmuir-Blodgett (LB) film method; secondly preparing a high-dielectric inorganic / organic composite nanoparticle film on the polymer dielectric film by the LB film method; and finally preparing a polymer dielectric film on the composite nanoparticle film by the LB film method, thereby forming a high-dielectric composite film material with nanoparticles dispersed in a polymer. The polymer-nanoparticle composite dielectric film material prepared by the method overcomes the shortcomings of the prior art, and the preparation method is reasonable and simple, and easy to operate.

Description

technical field

[0001] The invention relates to the field of electronic materials and components, in particular to a preparation method of a dielectric thin film based on a composite nanostructure. Background technique

[0002] High energy density capacitors are widely used in missiles and space fields, mainly for new electromagnetic pulse weapons (electromagnetic bombs and electromagnetic cannons) and electromagnetic energy weapons (electromagnetic rail guns and electromagnetic armor-piercing weapons), excimer Laser weapons, particle beam accelerators, high-power microwave sources, X-ray sources and other new concept weapons, strategic ballistic missiles, electromagnetic armor, etc. Due to the embargo imposed on my country by the United States of high energy storage density capacitors, the development of new electromagnetic energy weapons in our country is restricted.

[0003] In high energy storage density capacitors, the shape and performance of the dielectric materials ...
