In Situ Growth of Superhydrophobic Films on Aluminum Substrate

Abstract:

A facile and novel method was developed to fabricate highly porous CeO₂ surface on aluminum via a combination of homogeneous precipitation method and in situ growth process. After the introduction of CeO₂ film, aluminum exhibited excellent superhydrophobicity with contact angle of 152.9±1.5^o and a sliding angle of 5^o. SEM image of the film showed that the resulting surface exhibits a hierarchical micro- and nanostructure, which comprised of nanoleaves that grew perpendicular to the substrate and interleaved together to form a highly porous structure. This porous architecture, along with the low surface energy renders the aluminum superhydrophobicity.
