Abstract

The invention provides a preparation method of an energy-saving flexible transparent conducting film. After the film is formed, no high-temperature annealing is needed, thereby lowering the energy consumption; and the film crystallization degree is up to 80%, and thus, the method is suitable for large-scale industrialized production. The method uses a plurality of magnetron sputtering devices in one vacuum coating cavity, wherein each magnetron sputtering device comprises a sputtering cavity which uses inert gas as working gas and oxygen as reactant gas, and a target positioned in the sputtering cavity; a continuously moving flexible transparent substrate sequentially passes through the sputtering cavities of the target drones, wherein the temperature of the flexible transparent substrate is less than 80 DEG C; and by controlling the flow rates of the oxygen and inert gas introduced into the sputtering cavities, the target or target oxide is deposited on the flexible transparent substrate at one time. The invention also provides an energy-saving flexible transparent conducting film with high light transmittance, low resistivity and low chromatic value, which comprises a flexible transparent substrate, and a SiO2 layer, a Nb2O5 layer, a Nb2Ox layer (x=4.5-4.98), a SiO2 layer, a silver layer or copper layer and a semiconductor oxide layer which are sequentially deposited on the flexible transparent substrate.

Description

technical field [0001] The technology of the invention relates to an energy-saving flexible transparent conductive film and a preparation method thereof. The flexible transparent conductive film is widely used in the manufacture of flexible display devices, flexible smart touch screens, and flexible thin-film solar cells. Background technique [0002] Flexible transparent conductive films are widely used in flexible displays, thin-film solar cells, smart window films, touch screens and other fields due to their unique characteristics of flexibility, lightness, and high transmittance. [0003] At present, tin-doped indium oxide (ITO) is used as a transparent conductive thin film material, and it is widely used because of its mature manufacturing and application technology. However, due to its characteristic requirements, its optimum film-forming temperature is around 300°C. However, for flexible, ultra-thin transparent substrate materials (such as PET), the substrate materia...
