Preparation method of flexible transparent electrode

Abstract

The invention provides a preparation method of a flexible transparent electrode. The method comprises the steps of firstly preparing a PEDOT / PSS mixed solution and a silver nanowire mixed solution andthen mixing the PEDOT / PSS mixed solution with the silver nanowire mixed solution; adding a catalyst, an alcohol solvent and a stabilizer and stirring in a constant-temperature bath under a sealing condition to obtain a coating solution with appropriate viscosity; and finally coating a substrate with the coating solution and carrying out curing treatment to obtain the flexible transparent electrode. The method has the beneficial effects that the antioxidant capacity of silver nanowires is improved, and meanwhile, excellent conductivity and mechanical property of the silver nanowires are reserved; a silver nanowire transparent conductive film can be internally arranged to replace an ITO transparent conductive film, so that the manufacture process is simple; the requirements of new technologies, such as touch and flexible display can be met; traditional equipment for an ITO transparent conductive material and the material cost are reduced; and the reliability of a product is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for preparing a flexible transparent electrode. Background technique [0002] LCD (Liquid crystal displays, liquid crystal display) is a widely used flat panel display, which mainly realizes picture display by modulating the light field intensity of the backlight source through liquid crystal switches. LCD display devices include TFT (ThinFilm Transistor, thin film transistor) devices, and TFT-LCD is a thin film field effect transistor liquid crystal display. Each liquid crystal pixel on this type of display is driven by a thin film transistor integrated behind it. , so it has the characteristics of high response speed, high brightness, high contrast, small size, low power consumption, and no radiation, and occupies a dominant position in the current display market. [0003] The transparent electrode in LCD is a thin film material with high conductivity and high visibl...

Problems solved by technology

Among them, since the nano-silver wire is extremely easy to be oxidized, the conductivity and transmittance of the oxidized nano-silver wire will decrease significantly.

The existing application of nano-silver wire is mainly to coat a protective layer on the surface of nano-silver wire film to block the air; and the existence of the protective layer limits its application in some fields, such as replacing ITO in LCD As an application of liquid crystal display; in addition, because the protective layer usually needs hundreds of nanometers, and the trend of LCD thinning has become more and more obvious in recent years, the existence of the protective layer will significantly increase the thickness of the LCD cell; and the existence of the protective layer will also increase The distance of the electric field in the LCD has an unnecessary impact on the rotation of the liquid crystal; finally, it is unknown whether the addition of the protective layer will react to the alignment layer and the liquid crystal
