dc.description.abstract | We present a novel approach to produce high-resolution reduced graphene oxide (rGO) micropatterns based on a dewetting phenomenon of liquid thin films. The uniform liquid thin film of aqueous graphene oxide (GO) dispersion was formed by the meniscus dragging deposition method on a pre-patterned silanized substrate. Subsequently, selective dewetting of the water layer was induced due to the surface energy gradient on the coating substrates. After drying and chemical reduction, the high-resolution rGO micropatterns with a minimum feature size of 10 μm were realized over a large area substrate by consuming less than 1 μL of GO solution per square centimeter. As a demonstration of the application of this patterning technique, we have successfully fabricated organic field-effect transistors (OFETs) based on rGO pattern arrays as source-drain electrodes. The OFETs with the rGO electrodes exhibited a field effect mobility of 0.6 cm2 (V s)−1 with an on/off ratio of 1.79 × 106, which is higher than that of the devices with Au source-drain contacts. © The Royal Society of Chemistry. | - |
