Conductive polyimide thin films and their preparation methods
This application provides a conductive polyimide film and its preparation method, belonging to the field of conductive materials. The method involves preparing a polyamic acid solution, mixing surface-coated rod-shaped silver powder with the polyamic acid solution, and then performing a casting process followed by gradient heating to obtain a polyamic acid film enriched with rod-shaped silver powder at the bottom. The rod-shaped silver powder-rich surface of the obtained polyamic acid film is then subjected to an ion exchange reaction with a silver nitrate solution. The ion-exchange film is then cleaned and subjected to thermal imidization treatment to obtain the conductive polyimide film. This application utilizes the ion exchange reaction and subsequent thermal curing process to reduce silver ions on the film surface, forming a silver-plated layer with excellent adhesion and conductivity. This material exhibits excellent reliability during use; even if the surface silver-plated film partially peels off due to wear, the conductive network built by the rod-shaped silver powder at the bottom can still serve as a backup conductive path, significantly improving its long-term stability in practical applications.
