Polystyrene/octadecyltrichlorosilane superhydrophobic coatings with hierarchical morphology

A simple, one pot dip-coating process for the fabrication of superhydrophobic coatings using polystyrene (PS) and octadecyltrichlorosilane (OTS) is introduced. The hierarchical coating morphology and the resulting surface wettability were controlled by OTS concentration and by the number of dipping cycles. The coatings showed good durability for applications.
