Conductive Inks
Indium tin oxide (ITO) has long been the standard for transparent conductive films, but it's brittle, expensive to process, and incompatible with the flexible, large-area devices that define next-generation electronics.
Nano-C's Invisicon™ SWCNT and hybrid-SWCNT inks are engineered to address these limitations, delivering superior flexibility, conductivity, and optical performance compatible with spray, inkjet, and roll-to-roll coating methods.
Flexibility and conductivity without the constraints of ITO.
Built for Flexible, Large Area Applications
Invisicon™ inks achieve 99% optical transparency while maintaining high conductivity, performing reliably under mechanical stress and repeated flexing. This makes them well-suited for the demanding requirements of foldable displays, wearable devices, and large-area thin-film applications where ITO's brittleness is a fundamental constraint.
Because Invisicon™ inks are solution-processed, they eliminate the need for vacuum deposition equipment and high-temperature processing, reducing both capital investment and production costs. They are compatible with spray, inkjet, and roll-to-roll coating techniques, integrating directly into established manufacturing workflows.
