title: Facile fabrication of corrosion-resistant superhydrophobic and superoleophilic surfaces with MnWO(4):Dy(3+) microbouquets.
abstract: Superhydrophobic and superoleophilic MnWO4:Dy(3+) microbouquets were successfully fabricated via a facile hydrothermal process. The surface morphologies and chemical composition were investigated by scanning electron microscopy (SEM) and X-ray powder diffraction (XRD). The wettability of the as-synthesized MnWO4:Dy(3+) microbouquet film was studied by measuring the water contact angle (CA). A static CA for water of 165° and a very low sliding angle (SA) were observed, which were closely related to both the MnWO4:Dy(3+) microbouquet structure and chemical modification. Furthermore, the as-prepared MnWO4:Dy(3+) surface showed superhydrophobicity for some corrosive liquids such as aqueous basic and salt solutions.
