Tunable surface wettability and water adhesion of Sb2S3 micro-fnanorod films
Antimony sulfide ( Sb2 S3) films were successfully prepared by spin coating Sb2 S3 micro-/nanorods with different sizes on glass slides, which was synthesized via a facile and rapid microwave irradiation method. The prepared 513253 micro-/nanorods and films were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM) and water contact angle (CA). The as-prepared 5b253 films exhibited different surface wettabilities ranging from superhydrophilicity to superhydrophobicity, which was strongly dependent on the diameter of Sb2 S3 micro-/nanorod. Sb2 S3 film made by nanorods possessed superhydrophobic surface and high water adhesive property. After surface modification with stearic acid, the superhydrophobic surface exhibited an excellent self-cleaning property owing to its low adhesive force. The clarification of three possible states including Wenzel's state, "Gecko" state and Cassie's state for Sb2 S3 film surfaces was also proposed to provide a better understanding of interesting surface phenomena on Sb2 S3 films.
