Surface energy engineered, high-resolution micropatterning of solution-processed reduced graphene oxide thin films

Abstract

Fast and reproducible patterning of high-resolution rGO microstructures over a large area directly on various substrates by modulating the surface energy is reported. The pattern formation of rGO thin films is based on the difference in the adhesion strength between the mold/rGO and rGO/substrates interfaces. Such highly defined rGO micropatterns are applied as electrodes for high-performance flexible and transparent OFETs. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
