Abstract
An electronic textile (e-textile) was fabricated for use in NO2 gas sensor, using graphene oxide (GO) and commercial silk fabric (CSF) (GO-CSF). After thermal reduction at 400, 500, 600 ?꼦, the gas sensing property of the e-textiles (rGO-CSF) was measured for NO2. The morphology, structure, microstructure, and chemical components of the GO-CSF and rGO-CSF were analyzed by scanning electron microscope, x-ray diffraction, Raman spectroscopy, transmission electron microscope, and x-ray photoelectron spectroscope. Gas sensing properties were investigated by exposing rGO-CSF samples to 1, 5, and 10 ppm of NO2 gas at room temperature. The best sensing performance was shown by the rGO-CSF reduced at 400 ?꼦, which was attributed to the large surface area and optimum pore size. Also, performance was stable under bending.
