Abstract
The first electrochromic cyan/magenta/yellow (CMY) inks based on conjugated polymers have been formulated and inkjet printed. Through tuning solution and substrate properties, this study demonstrates the ability to print well-resolved droplets and lines that result in high-quality films. Fine-tuning of coloration is accomplished by layering CMY inks and varying drop density, offering a large palette of colored-to-colorless electrochromic films.
