Abstract
The present invention relates to a flexible and transparent electrode and manufacturing method thereof. The flexible transparent electrode comprises an insoluble polyimide film as a substrate and metal nanowires as a conductor, wherein the insoluble polyimide film is polymerized by aromatic diamines and alicyclic diamines of thermal imidization. In addition, the coating method of polyimides of the present invention not only improves the adhesion and dispersion between metal nanowires and substrate, but also exhibits good thermal stability; moreover, the transparent electrode keeps the effectiveness even in high temperature processing conditions such as annealing, laser, plasma or other severe operation environment. Using the step transfer printing method can produces the transparent electrode product with smooth surfaces, thermo stability, and organic solvent resistance, so as to improve the adhesion of metal nanowires and lower the resistance of the transparent electrode.
