Investigation of Coated Indium Tin Oxide Conductive Film

Abstract

Flexible indium tin oxide (ITO) film has good optical and electrical properties, and is lightweight and flexible, which is why it has become the focus of research into flexible electronic devices. Coating methods for preparing flexible ITO film can help cut costs but ITO film manufacturing technology needs to be optimized as well. To solve this issue, we tested a series of experiment parameters. The results indicate that well-performing ITO films can be prepared by heating them for two minutes at 100 ℃ with Mayer rod of RDS No. 20. The sheet resistance of the ITO film can reach up to 578 Ω/sq and keep a transmittance of 70%.
