Electronic textile-based gas sensors with a high response for NO2 were fabricated using reduced graphene oxide (rGO)-coated commercial cotton fabric (rGOC). Graphene (GO) was coated on by simply dipping the into GO solution. To investigate relationship between degree of reduction and sensing response, GO-coated fabrics thermally at various temperatures (190, 200, 300, 400 °C). The change in amount oxygen functional groups rGOCs observed x-ray photoelectron spectroscopy, Raman diffraction patterns. maximum 45.90 % 10 ppm room temperature exhibited rGOC treated 190 °C, which lowest heat-treatment temperature. comes from greater compared to other samples, tubular structure cotton.
