Manufacturing method of externally-convex transparent conductive film

Abstract

The invention relates to the micro nano printing technology field and especially relates to a manufacturing method of an externally-convex transparent conductive film. The method comprises the following steps of manufacturing a base material; directly filling a conductive material in a uv structure groove through a micro-nano printing mode; transferring the conductive material in the groove to a surface of a transparent base material to form a transparent conductive film through static electricity and viscosity of a uv glue in an uv transfer printing mode; coating a uv resin, preparing a pet optical bare material or other optical base materials after one embedded transparent conductive film is manufactured; coating the uv resin on the pet optical bare material or the other optical base materials or the embedded conductive film; and laminating the two materials in a same-size ratio manner, and then carrying out roller impressing. In the invention, advantages of a small resistance and strong conductivity are achieved, a conductive layer is directly based on an optical material without interference of other media, simultaneously a phenomenon that a waste liquid in yellow photoetchingpollutes an environment is avoided, pollution to the environment is prevented, production cost is reduced, and losses of a source material are reduced.

Description

technical field [0001] The invention relates to the field of micro-nano printing technology, in particular to a method for preparing a convex transparent conductive film. Background technique [0002] Transparent conductive film is a kind of film that can conduct electricity and has high transparency in the visible light range, mainly including metal film system, oxide film system, other compound film system, polymer film system, composite film system, etc. [0003] Conventional transparent metal conductive films are mostly realized by printing conductive ink after yellow photolithography or uv transfer printing structure. The cost of the former is high, and its waste liquid has an impact on the environment and wastes a lot. The production process of the latter is complicated and due to the conductive material It is hidden inside the uv structure and cannot be in direct contact with external materials, so the conductivity is relatively poor. The present invention further ex...
