Functionalization of carbon nanotubes proceeds by using atmospheric pressure non-thermal plasma treatment, where NH3 is used as nitrogen sources which is excited either by alternating currents (AC) or direct currents (DC). The content and species of the functional groups are analyzed by XPS which displays that heteroatom content increases 1.6 at.%, the main nitrogen groups are pyridinic nitrogen (N-6) and amino (-NH2), and HO-C=O, C=O and C-OH surface groups are also incorporated. The supercapacitive performance of the pristine CNTs, CNT-DC and CNT-AC electrodes are measured and the specific capacitance of CNTs is increased after plasma treatment, which indicate that the surface functionalization facilitate the improvement on supercapacitive properties.
