The study of natural lotus leaves reveals that to obtain a super-hydrophobic surface with both a large contact angle (CA) and small sliding angle (α), cooperation of micro- and nanostructures is required. Accordingly, lotus-like aligned carbon nanotube (ACNT) films with a CA of ∼166° (see Figure) and α of ∼3° have been fabricated. Other super-hydrophobic surfaces of polymer nanofibers and different patterned ACNT films are also highlighted.
