Description

technical field [0001] The invention belongs to the technical field of conductive glass, and relates to a graphene oxide conductive glass and a preparation method thereof. Background technique [0002] At present, the conductive films of transparent conductive glass widely used in the industry mainly include indium tin oxide, zinc aluminum oxide and fluorine-doped tin oxide. Among them, the preparation of the indium tin oxide conductive film requires a large amount of expensive indium metal, which is a rare earth metal, and its material cost is relatively high, which greatly limits its application. The photoelectric properties of zinc aluminum oxide and fluorine-doped tin oxide films are similar to those of indium tin oxide films, but the preparation conditions of their conductive films are relatively harsh, usually by vacuum evaporation, magnetron sputtering, physical or chemical coating, etc. on the glass surface. The above-mentioned metal oxide conductive film can be mad...
