                         vertically aligned multiwalled carbon nanotube (VACNT) surfaces 
                         using the pulsed-discharge plasma technique. As-grown VACNT 
                         surfaces were superhydrophobic. Pure oxygen plasma etching 
                         modified VACNT surfaces to get a superhydrophilic behavior after 
                         only 2. min. Contact angle and surface energy measurements by the 
                         sessile drop method examined the VACNT surface wetting. X-ray 
                         Photoelectron Spectroscopy showed the heavy grafting of 
                         oxygen-groups onto VACNT surfaces after oxygen plasma etching. The 
                         results showed the great influence of polar groups on wetting 
                         behavior, with a strong correlation between the polar part of the 
                         surface energy and the oxygen content on the VACNT surfaces. These 
                         findings proved that oxygen plasma etching is a rapid and 
                         efficient method for functionalization of VACNT surfaces.",
