Characteristics of transparent conductive film on metal mesh

Metal mesh transparent conductive film has high conductivity and good transparency, and can achieve excellent transmittance in the visible light range. Because the metal grid has a regular structure, electrons can freely conduct through it, forming conductive channels. Compared with traditional ITO conductive films, metal mesh transparent conductive films have the advantages of low preparation cost, good flexibility, and strong tensile resistance, and are therefore highly favored by researchers and industry.

Preparation Method

1. Solution preparation: Metal nanoparticles are dispersed in a solvent and metal grids are prepared on a substrate through methods such as solution spin coating and immersion. This method is simple, low-cost, and suitable for the preparation of large-area thin films, but there are still problems such as irregular grid structure and poor conductivity.

2. Vacuum evaporation method preparation: Using vacuum evaporation technology, metal materials are evaporated on the substrate surface to form a grid structure. The metal mesh transparent conductive film prepared by this method has high optical transparency and conductivity, but the equipment is complex and the cost is high, making it suitable for devices with small areas and high requirements.

3. Laser etching method preparation: Using laser technology to etch grid structures on the surface of metal thin films. The conductive film prepared by this method has the characteristics of high precision and strong controllability, but the preparation process is complex and the cost is high.
