Problems solved by technology

At present, the transparent conductive film with DMD structure is easy to deteriorate or even fail due to the oxidation of the metal layer in the subsequent processing process.
Moreover, the color of the transparent conductive film of the existing DMD structure deviates from the neutral color, which is not suitable for applications in the construction field such as smart windows.

Abstract

The invention provides a high-temperature-resistance composite transparent conducting film and a preparation method thereof, and belongs to the technical field of conducting films. The high-temperature-resistance composite transparent conducting film is characterized in that an ion barrier layer (1), a buffer layer (2), an inner-layer metal protecting layer (3), a metal layer (4), an outer-layer metal protecting layer (5) and a functional layer (6) are sequentially arranged on the upper surface of a transparent base plate (7) from inside to outside, so that a layered structure is formed; the inner-layer metal protecting layer (3) and the outer-layer metal protecting layer (5) are each prepared from Ti, Cu, Al, Ni, Nb, V, Cr, nickel-chromium-vanadium alloy, vanadium-titanium alloy, aluminum-titanium alloy, aluminum-nickel alloy, nickel-chromium alloy, aluminum-vanadium alloy or copper-chromium alloy. The thickness of the inner-layer metal protecting layer (3) and the outer-layer metal protecting layer (5) is 0.2nm to 1.5nm. The layers are prepared on the transparent base plate in sequence through a magnetron sputtering method. The conducting film can be tempered and is neutral in color permeation, low in haze and resistant to high temperature.

Description

technical field [0001] A high temperature resistant composite transparent conductive film and a preparation method thereof belong to the technical field of conductive films. Background technique [0002] Transparent conductive film (TCO) is a film with high transparency and conductive properties in the visible light range. It is mainly used in transparent electrodes in flat-panel TVs, touch screens, smart window glass, light-emitting diodes, and photovoltaic cells. [0003] Among the transparent conductive films, the most widely used one is tin-doped indium oxide film, commonly known as ITO film. According to reports, when the ITO film thickness is 366nm, the sheet resistance is about 66Ω / £. The deposition rate of ITO is very small, and it is necessary to increase the thickness of ITO in order to achieve below 10Ω / £. The color deviates from neutral and takes on a yellowish tint. In order to solve the dependence on ITO, the development of doped zinc oxide, carbon-based tra...
