Ultrasonic spraying stands as an efficient thin-film fabrication technique for depositing nanoscale conductive coatings on glass substrates. High-frequency ultrasonic vibration atomizes conductive raw materials including silver and indium tin oxide (ITO). The atomized droplets are uniformly deposited onto glass surfaces to form nanoscale conductive films, endowing the finished glass products with excellent electrical conductivity and optical transparency. This ultrasonic coating method for nanoscale conductive glass films is primarily applied in three fields: touchscreen production with transparent conductive layers, solar cell fabrication utilizing transparent electrode materials, as well as assorted electronic components requiring conductive interconnect structures.

 

 

 

 

 

 

1. Material Selection
Common conductive materials adopted for the process include indium tin oxide (ITO), indium-doped zinc oxide (ZnO), and silver nanowires. A matched solvent is selected to ensure these conductive materials disperse evenly and stably in the solution.

2. Equipment Configuration
The spraying system consists of core ultrasonic spraying units, including an ultrasonic generator, atomizing nozzle and liquid supply system. A dedicated substrate fixture is equipped to firmly fix glass substrates and avoid displacement during continuous spraying, guaranteeing processing stability.

3. Spraying Parameter Setting
High-frequency ultrasound is applied to deliver fine and uniform atomization for high-quality coating formation. The spraying pressure is precisely calibrated to stabilize the spraying rate and improve coating uniformity. Meanwhile, the nozzle-to-substrate distance is adjusted to a reasonable range, ensuring consistent deposition of nanoscale conductive coatings on the glass surface.

4. Spraying Process Flow
First, preprocess the glass substrate by thorough cleaning to remove surface dust, oil stains and impurities. Next, prepare the spraying solution by dissolving conductive materials in the matched solvent and adjusting the solution concentration to meet standard spraying requirements. After equipment debugging, initiate the ultrasonic spraying system to uniformly deposit conductive materials on the substrate surface and form a complete nanoscale coating. Finally, cure the coating via thermal heating or UV irradiation, which effectively enhances the coating's surface adhesion and electrical conductivity.
