Abstract: Fabrication of carbon nanotubes (CNTs) field emitter arrays (FEAs) on flexible substrate was demonstrated with a novel microfabrication technique, namely, reversal roller imprint lithography (RRIL). In this process, CNTs paste was inkjetted coating onto a patterned roller mould and squeezed into the microstructures of the roller mould by an elasticity scraper, and then it was transferred to the flexible substrate with a suitable contact pressure. The field emission measurement showed that the turn-on field was about 2.3 V/?m at the emission current density of 10 ?A/cm2. This process was suitable for the fabrication of flexible electronic devices with CNTs.
