Functional Coatings

Ultrasonic Dispersion of Nanoparticles for Electrically Functional Coatings

Compared to other coating methods, ultrasonic spray coating has  significant advantages for functional coatings on glass such as TCO (transparent conductive oxide coatings, CNTs (carbon nano tubes) and silver nanowires. Siansonic ultrasonic nozzles are very suitable for spraying suspensions with electrically active particles, dispersing solid particles in suspensions evenly to achieve outstanding electrical performance.

Typical functional coatings deposited onto various types of glass, plastics, and metals by Siansonic ultrasonic coating systems

• Transparent Conductive Oxide coatings

• Photoresist coatings

• Electrochromic coatings

• CNT or Nanowire coatings

• Anti-reflection (TiO2, SiO2) coatings

• Hydrophilic and hydrophobic coatings

Larger and thinner active layers with greater electrical properties can be achieved due to uniform dispersion of particles. Produce large area coatings with high uniformity at a fraction of the cost of CVD and sputtering processes. Highly controllable spray by siansonic ultrasonic nozzles can realize selective area coating processes which is almost impossible by using other coating methods.
