High-response room-temperature NO gas sensor fabricated with thermally reduced graphene oxide-coated commercial cotton fabric.

Electronic textile-based gas sensors with a high response for NO gas were fabricated using reduced graphene oxide (rGO)-coated commercial cotton fabric (rGOC). Graphene oxide (GO) was coated on cotton fabric by simply dipping the cotton into a GO solution. To investigate the relationship between the degree of reduction and the sensing response, the GO-coated fabrics were thermally reduced at various temperatures (190, 200, 300, and 400 °C).
