Preparation method of embedded metal mesh transparent conductive film

1. Preparation of materials

Before preparing transparent conductive films with embedded metal grids, the corresponding materials need to be prepared first. Mainly including conductive metal nanoparticle solution, glass substrate, transparent conductive oxide film, etc. The selection and preparation of these materials are crucial for the subsequent preparation process, ensuring that their purity and quality meet the requirements.

2. Preparation of metal nanoparticle solution

Dissolve selected conductive metals (such as silver, copper, etc.) in organic solvents and prepare metal nanoparticle solutions through appropriate physical or chemical methods. This step is the basis for preparing transparent conductive films with embedded metal grids. The uniform dispersion and stability of metal nanoparticles will directly affect the conductivity of subsequent films.

3. Preparation of Transparent Conductive Oxide Thin Films

Sol gel method or magnetron sputtering is usually used to deposit transparent conductive oxide films on substrate materials. The key to this step is to control the thickness and crystallinity of the film to ensure its transparency and conductivity.

4. Embedded metal mesh structure

Uniformly spray the prepared metal nanoparticle solution onto the surface of a transparent conductive film, and form a grid like structure on the film surface through heat treatment or chemical treatment. This structure ensures the transparency of the film and improves its conductivity, making it the core preparation step for embedded metal mesh type transparent conductive films.

5. Film performance testing and optimization

After preparation, perform performance tests on the embedded metal grid type transparent conductive film, such as transmittance, conductivity, durability, etc. Based on the test results, continuously optimize the preparation process to improve the quality and performance of the film.

conclusion

Embedded metalGrid type transparent conductive filmThe preparation method has brought new ideas and solutions to the current field of transparent conductive films. By selecting materials reasonably and controlling the preparation process accurately, stable and low-cost conductive thin films can be prepared, providing reliable support for the development of electronic products. I hope this article can provide some useful references and inspirations for research and practitioners in related fields.
