Schematic of the CNT treatment system with a digital image of plasma. The inset shows the comparison of CNT dispersions in water before and after plasma treatment for .
SEM and TEM images of CNTs. SEM micrographs of CNTs (a) before and (b) after plasma treatment. TEM images of CNTs (c) before and (d) after plasma treatment. The samples in (b) and (d) were plasma treated for .
XPS C and F spectra of the untreated and treated CNT powders.
Time sequence images of a water droplet free falling on CNT cushions. (a) Untreated CNT cushion in which the droplet finally penetrates through the cushion. (b) treated and (c) treated CNT cushions in which the droplets eventually bounce off the cushions. The white arrows indicate the upward and downward directions of the water droplet.
Pore size and contact angle values for untreated and plasma-treated CNT powders obtained from the Washburn equation. The surface free energy components of the CNT powders were calculated from the van Oss-Chaudhury-Good equation.
