Abstract
The present disclosure provides a preparation method of the electroconductive polyimide and a display panel. The preparation method may include: providing aminated carbon nanotubes; and mixing the aminated carbon nanotubes with diamine and dianhydride in a predetermined reaction condition to form a mixture, such that the aminated carbon nanotubes react with the diamine and the dianhydride to generate the electroconductive polyimide. According to the above method, the electroconductive polyimide can be prepared through the reaction between the aminated carbon nanotubes, the diamine, and the dianhydride.
