Superhydrophobic coating fabricated by electrophoretic deposition using polydimethylsiloxane-based organic–inorganic hybrid materials and ceramic powders

Abstract

Superhydrophobic surfaces have important applications in daily lives as well in various industries. In this study, composites with superhydrophobic surfaces were fabricated from polydimethylsiloxane-based hybrid materials and ceramic nanopowders by electrophoretic deposition. Under different appropriate conditions, such as the amount of a particular component, the composite possessed a three-layered hierarchical surface. The fabricated composite films comprising three-layered hierarchical structures exhibited contact angles greater than 160° and contact angle hystereses as well as sliding angles less than 5°.
