Description
technical field [0001] The invention belongs to the intersection field of computers and nanometer materials, and in particular relates to a polyimide-based nanocomposite film breakdown field strength prediction model and its construction method and application. Background technique [0002] Polyimide-based composite films are a hot issue in the research of nanocomposites, which have the advantages of both traditional insulating films and modern nanomaterials. Compared with traditional polyimide films, polyimide-based nanocomposite films can effectively improve the electrical properties of the film, such as corona resistance, breakdown field strength, dielectric constant and dielectric loss, resistivity and conductivity. Significantly improve the insulating performance of polyimide film. At present, researchers have turned from a single material (organic or inorganic) nano-film to a nano-composite film (organic-inorganic), and the thickness of the film has grown from micron ...
