| titleOfInvention | A kind of nanocomposite porous polyimide film and preparation method thereof |
| abstract | The invention discloses a nano-composite porous polyimide film and a preparation method thereof. The porous polyimide film is prepared by the following preparation method: 1) reacting nanoparticles with a silane coupling agent to obtain modified nanoparticles; 2) dissolving polyimide and auxiliary additives in an organic solvent , obtain a polyimide solution; 3) mix and disperse the polyimide solution and the modified nanoparticles, and then add water to mix and emulsify to obtain Pickering emulsion; 4) Coat the emulsion on the substrate and dry to obtain . The preparation method of the invention has the characteristics of mild conditions, low cost, simple operation process and technology, and the like. Due to the selection of water droplets and modified nanoparticles, it is not only cheap but also does not require additional steps to remove pores, which can introduce pores in the polyimide film and reduce the dielectric constant. At the same time, the addition of nanoparticles can also improve the mechanical properties of the film. Used in electronics, microelectronics, aerospace and other industries. |
