Tailoring the surface properties by varying the chemistry and roughness could be of
interest for self-cleaning applications. We demonstrate the transformation of hydrophobic
ZnO Nano rod (NR) array into superhydrophobic nature by changing the local chemical
state and without altering the surface roughness by swift heavy ion (SHI) irradiation.
The aligned ZnO NR arrays were irradiated using 150 MeV Ag ions with different fluences
from 5E10 to 3E12 ions/cm<sup>2</sup>. The observed static water contact angles of
ZnO NRs samples were 103° ± 3°, 152° ± 4°,161° ± 3°, 164° ± 2°, 167° ± 2°,154 ± 3°
and 151° ± 2° for the pristine, ion fluencies of 1E11, 3E11, 5E11, 7E11, 1E12 and
3E12 ions cm<sup>−2</sup>, respectively. The change in local surface chemistry via
formation of surface oxygen related defects due to electronic excitations induced
by ion irradiation determine the water dewetting properties. It is found that surface
oxygen related defects could be tuned by varying the fluence of the SHIs. Durability
tests show that the SHI induced surface oxygen-deficient ZnO NRs have the stable superhydrophobic
behavior for more than a year. |
