Original Abstract

Sensors based on multi-walled carbon nanotubes were functionalized by oxygen plasma treatment and plasma co-polymerization of maleic anhydride and acetylene, obtaining core-shell carbon nanopartices covered by functional groups. The active nanostructured carbonaceous material was investigated by scanning electron microscopy, energy dispersive X-ray spectroscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy. It was confirmed that plasma treatment increases the content of surface functional groups. The sensing properties of the functionalized material were measured in the range of 10–1000 ppm of NH3 at room temperature. The plasma treated sensor showed an extremely high response of 22.5%, 27.9%, and 31.4% to 100 ppm, 250 ppm, and 500 ppm of NH3, respectively. It was shown that the nature of NH3 adsorption on the surface of functionalized nanostructured carbon material is physical adsorption.
