Abstract
Flexible gas sensors with high-sensitivity and good stability are essential components of wearable electronic devices. In this paper, we present a novel graphene fabric gas sensor composed of reduced graphene oxide (RGO) nanosheets and electrospun nylon-6 nanofibers. By combination the RGO with nanofiber, the graphene electronic fabrics show sensitive response to NO2 (13.6%@1 ppm) at room temperature, and excellent mechanical reliability against repeated deformation during 5000 bending cycles with an extreme bending radius of 1.0 mm.
