▎ 摘　　要

NOVELTY - The electrode has a flexible supporting layer (1) sequentially arranged on a high-conductivity transmission layer (2) and a dielectric protective layer (3), where the flexible supporting layer is made of high polymer material arranged on a bottom layer. The dielectric protective layer is made of transparent conductive oxide material arranged on a top layer. The high-conductivity transmission layer is made of metal and/or carbon material arranged between the flexible supporting layer and the dielectric protective layer. The high-conductivity transmission layer is a graphene silver film. The flexible supporting layer is a polyimide film. The dielectric protective layer is a metal aluminium doped zinc oxide film, and a fluorine-doped tin oxide film. USE - Flexible multi-layer composite transparent electrode used in display, electroluminescent device and solar cell. Can also be used in large-area touch screen. ADVANTAGE - The electrode has good stability and photoelectric performance, and high conductivity transmission layer and dielectric protective layer design well solves the problem that the traditional transparent conductive indium tin oxide is hard and brittle, the bearing deformation is very small, and the metal silver with good conductivity is very active, the metal nanowire or metal grid structure has large specific surface area, once the oxide transparent electrode is invalid. The copper nanowire yellowing index is too high, reflecting and easy to form the problem of moire. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing flexible multi-layer composite transparent electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a flexible multi-layer composite transparent electrode. 1Flexible supporting layer 1.1High conductivity transmission layer 2High-conductivity transmission layer 2.2High-conductivity transmission layer 3Dielectric protective layer 3.1Dielectric protective layer
