Novel method for efficiently changing the surface characteristics and density of vertically aligned carbon nanotubes (CNTs) using Ar plasma irradiation is proposed in this study. The influence of work volume on the surface characteristics and density was evaluated. The wettability of CNTs was determined by measuring the contact angle. Evaluation of the crystallinity and density were carried out using Raman spectroscopy and scanning electron microscope (SEM), respectively. Before irradiation, the CNTs behaved as hydrophobic surface for the purified water, and coverage of CNTs on the surface exceeded 95 percent. After the irradiation at low dose, the contact angle decreased from 145 to 0 degrees. While the work volume increases, the rate of coverage can be reduced to 40 percent within 30 minutes. In the case of irradiation at low dose, Raman spectrum change was little. In contrast, the Raman spectrum change was larger in the case of irradiation at high dose.
