Abstract

Patterning oriented reduced graphene oxide (rGO) into functional structures is significant for its application in electronics and sensors. A large array of highly oriented rGO microbelts are prepared by a soft lithography process. These rGO microbelts have a uniform structure that enables the massive production of graphene electronics using a simple mask shielding process. A high performance NH 3 sensor array which was fabricated from rGO microbelts exhibits a reproducible performance with the relative resistance response (ΔR/R 0 ) reaching 0.35, whilst offering a large concentration range response of 10 ppm ∼38%, showing these sensors to be both highly sensitive and responsive. The impact of working temperature on the response to NH 3 in low and high concentration ranges of NH 3 is also discussed. © 2013 IOP Publishing Ltd.
