Abstract
The invention discloses a method for preparing a polyimide thin film with low friction coefficient and high cohesive force, and belongs to the technical field of electronic thin film insulating material preparation. During the preparation process, a composition of a filtering material and a dispersing agent of which the mass ratio is (10:1)-(1:1) is used, the filtering material is microscale or nanoscale spherical organosilicone, silicate, aluminum-oxygen compound or calcium phosphate filtering material and the like; the dispersing agent is polyphosphate or polyacrylic acid compound or composition; every 100 parts of a polyamide acid resin liquid (solid content) by weight uses 10-20 parts of the composition of the filtering material and the dispersing agent by weight. Through the addition of the microscale filtering material, the internal performance of the thin film is improved, the surface roughness of the thin film is increased, the mechanical occlusion action of the thin film and the coating surface and the adhesive force of the thin film and the coating are enhanced, the wettability and the adhesion are greatly improved, so that the working efficiency is effectively improved, the product quality is optimized, and the suitability and the reliability of the thin film in various fields can be improved.
