Abstract

Based on graphene oxide and reduced graphene oxide, a novel gas sensor was fabricated with layer-by-layer self-assembly techniques. The negatively charged graphene oxide sheets and the positively charged reduced graphene oxide sheets were layer-by-layer assembled on positive Au electrodes. The gas sensor exhibited a 1.83% of resistance difference before and after exposure to 20 ppm of dimethyl methylphosphonate (DMMP). The sensor showed a good repeatability, and the recovery time was about 4 min. Above all, the unique properties, such as simplicity of production process, the easy availability of the materials and the good response to DMMP vapor, endow the device a great potential for sensing application.
