Abstract

The invention relates to the technical field of conductive materials, and specifically relates to a preparation method of a flexible transparent conductive film. The preparation method includes the steps of applying a layer of imprinting glue to the end face of a flexible transparent substrate; imprinting a micro-nano cylindrical array pattern on the imprinting glue; removing the imprinting glue between two cylinders to expose the flexible transparent substrate; depositing a metal film on the flexible transparent substrate and the imprinting glue; removing the imprinting glue on the flexible transparent substrate and the metal film on the imprinting glue to obtain a transparent conductive network. According to the invention, the flexible transparent conductive film is prepared by means of combining nano imprinting and film coating, the problem of wire breakage existing in the conductive film prepared according to the traditional nano-imprinting assisted method of filling nano-imprinting grooves by scrape coating metal conductive paste is overcome, the conductivity of the flexible transparent conductive film is improved, and the prepared flexible transparent conductive film is better in stability and high in finished product rate.

Description

technical field [0001] The invention relates to the technical field of conductive materials, in particular to a preparation method of a flexible transparent conductive film. Background technique [0002] Transparent conductive film (ITO) is a film that is both transparent and conductive. Because of its high transmittance and high conductivity in the visible light range, it has been used in the fields of light-emitting devices, photovoltaic devices, optical waveguides, sensors, flat-panel liquid crystal displays, electrochromic windows, electromagnetic shielding and anti-static films. widely used. With the development of science and technology, more and more electronic devices begin to develop in the direction of flexibility and ultra-thinness, which makes the demand for flexible transparent conductive films increasingly urgent. Flexible transparent conductive film not only has the photoelectric characteristics of glass substrate transparent conductive film, but also has ma...
