CARBON NANOTUBE PRINTED ELECTRONICS DEVICES

摘要

Electronic devices include a network of purified and randomly aligned carbon nanotubes. The electronic devices include conductive regions that comprise conductive inks, and substrates such as flexible plastic materials including PET. Networks of randomly aligned carbon nanotubes are exposed to UV radiation to convert metallic carbon nanotubes to semiconductive carbon nanotubes. Conductive regions are printed onto a substrate using printing techniques such as inkjet printing and gravure printing. Devices are fabricated at low temperatures, without annealing and without vacuum.
