| titleOfInvention | A preparation method of boron nitride and aluminum nitride co-doped polyimide composite film with high thermal conductivity and high insulation |
| abstract | The invention discloses a method for preparing a boron nitride and aluminum nitride co-doped polyimide composite film with high thermal conductivity and high insulation, which relates to a method for preparing the composite film. The purpose of the invention is to solve the problem that the existing polyimide composite film has poor thermal conductivity, insulation and mechanical properties, and its application in the electrical insulation field is limited. Preparation method: 1. Prepare ultra-thin boron nitride powder; 2. Prepare viscous polyamic acid solution containing ultra-thin layers of boron nitride and aluminum nitride; 3. Prepare composite film to obtain boron nitride and aluminum nitride Co-doped polyimide composite film with high thermal conductivity and high insulation. The thermal conductivity of the boron nitride and aluminum nitride co-doped polyimide composite film with high thermal conductivity and high insulation prepared by the present invention increases by 68% to 330%, the insulation resistance increases by 0.8 to 4.1 times, and the tensile strength increases 1% to 31%. The invention is suitable for preparing boron nitride and aluminum nitride co-doped polyimide composite films with high thermal conductivity and high insulation. |
