Abstract

Cobalt hierarchical structure having intrinsic superhydrophobic property is prepared via an electrochemical growth approach. The structure exhibits aesthetic flower-like morphology. A quenching strategy is employed to elucidate the plausible crystal growth mechanism. Without further hydrophobic organic molecule modification, the hierarchical structure occupying surface exhibits superhydrophobic effect, which is a new superhydrophobicity example achieved from the hydrophilic material. An approach based on computer graphics is utilized to simulate the contact pattern on this non-Euclidean hierarchical structure.
