Printed Electronics, Based on Carbon Nanotubes and Graphene Nanosheets

Printed electronics has attracted great consideration in recent years, both scientifically and commercially. The attention to printed electronics is attributed to the fact that they facilitate the production of low cost, flexible electronics on various substrates and in large scales. The main functional component of printed electronic inks, is the conductive nanoparticles that are incorporated into them. Among different conductive components that can be incorporated into printing inks, metal nano particles, metal nano wires, graphene nanosheets, carbon nanotubes and conductive polymers are more common. The reasonable properties and relatively low cost of graphene nanosheets and carbon nanotubes, provide them a considerable capability to be used in electronic applications such as sensors, semiconductors, transparent electrodes and flexible and printed electronics. Herein, different aspects and recent developments in printed and flexible electronics has been overviewed with the emphasize on utilizing graphene nanosheets and carbon nanotubes in printing inks.
