Conductive films can utilize materials across a wide swath of conventional technologies, with particular use of indium tin oxide (ITO).
About
This feature some-what limits use of these ITO-based films in combination, e.g., with flexible substrates.The present technology addresses concerns with ITO-based films to provide candidate materials for use in connection with flexible electronics, and encompasses films and material layers comprising poly(3,4 ethylenedioxytho-pene) (PEDOT). The PEDOT film is made utilizing vapor phase polymerization (VPP) with defined parameters and components. The crystalline structure is favorably organized for films to achieve conductivity in excess of 1000 S/cm, and thus suitable for use as a replacement for ITO-based films.
Key Benefits
• High Conductivity: in excess of 1000 S/cm, well-above most conventional technologies. Conductivity can be tailored based on the application • Transmittance: exhibits excellent transmission in excess of 85% • Reliability: outperforms both PEDOT:PSS and ITO in fatigue test of flexure dimension • Transparency: optically transparent and/or exhibits optical properties that transmit light through > 90% • Stretchability: very strechable, conductivity increases upon stretching
