Abstract: The surface wettability of ACNTs is important for the development of hybrid nano-materials to perform various functions. However, as-grown ACNTs are super-hydrophobic due to the large proportions of air trapping. By using O2 plasma etching, the surface wettability of ACNTs can be tuned from super-hydrophobic to hydrophobic, and then to hydrophilic by adjusting the flow rate of O2 gas during the etching process. Moreover, it was found that the surface wettability could be recovered by removing the top part of O2 plasma treated CNTs. Combining with laser-pruning technology, ACNT films with different kinds of patterns can be produced. Thus, CNT films with patterns of controlled wettability were produced and these can act as templates for the selective assembly of various nano-particles such as PS particles, CdTe quantum dots, and fluorescent particles.
