Problems solved by technology

In the process of preparing transparent conductive films, due to the poor high temperature resistance of the organic flexible substrate and the low glass transition temperature, it is easy to be damaged by ion bombardment and high temperature.
The crystallinity of the film obtained by the vacuum evaporation method is not good enough, and the adhesion to the substrate is small; when the transparent conductive electrode is prepared by the magnetron sputtering method, it is not easy to obtain a surface with high flatness; , etching and cleaning and other processes to pattern the transparent con

Abstract

The present invention discloses a flexible transparent film having a novel electrode structure and a preparation method of the flexible transparent film. The flexible transparent film comprises a film body. A surface of the film body is provided with a groove etched by using a picosecond laser. The groove is filled with conductive ink. After being solidified, the conductive ink forms an electrode. During preparation, a film body is placed on a two-dimensionally movable platform first; then, a groove is etched on the film body by using an ultraviolet fiber laser; and then, conductive ink is input into the groove, so that after being solidified, the conductive ink forms an electrode. The flexible transparent film of the present invention is high in product yield; the shape, the width, and the depth of the electrode can be conveniently adjusted to meet use requirements of different film products; and the flexible transparent film is widely applicable. The process of the preparation method of the flexible transparent film is simplified; the preparation costs and the preparation time of the product are greatly reduced; the control during preparation is easy; and parameters of the products are easy to adjust, ensuring that the products can meet different use requirements.
