Problems solved by technology

[0004] However, the graphene pattern layer obtained by the current laser-induced graphene (LIG) has weak mechanical properties. When the scotch tape test is performed, the graphene thin layer will be peeled off from the surface of the polyimide film. The conductivity of the area itself is poor, and often needs to be enhanced by screen printing silver paste, but the operation of screen printing silver paste is difficult, and the accuracy of the printing area is poor
In addition, the existing laser-induced graphene research is mainly applied in the laboratory environment, and an inert gas environment must be provided during the induction process of some materials, which is not conducive to the industrialization of laser-induced graphene (LIG) in the production of flexible electronic devices.

Abstract

The invention discloses a manufacturing method of a flexible electronic device based on LIG, which is characterized by comprising the following steps: step S200, a graphene image is formed on one surface of a base material based on an LIG technology to serve as an induction layer; a graphene image is prepared on the other side of the base material based on the LIG technology to serve as a drivinglayer, and the LIG technology is the laser induction technology of a short-wavelength laser light source; the sensing layer and the driving layer are synchronously prepared; in the preparation process, a first laser light source and a second laser light source are arranged on a base material, light rays of the first laser light source and the second laser light source are parallel, the first laserlight source and the second laser light source move in the front-back direction, the base material moves in the left-right direction, and preparation of a graphene preparation image is completed through cooperation. According to the invention, each processing step of the single-layer substrate film is sequentially completed on the conveying line belt, and a double-sided synchronous processing method is adopted, so that the processing efficiency can be ensured, the manufacturing cost of the graphene flexible device is reduced, the structure that a graphene pattern is easy to damage is changed,and the graphene pattern is protected.
