Abstract: A copper sulfide film with dual scale micro- and nano-structured roughness was constructed on copper foil via a facile solution-phase method using the sodium thiosulphate and cupric chloride as raw materials. The resulting film was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) spectrometer, and contact angle measurements. After stearic acid hydrophobization, the film exhibited a water contact angle of 161° and a sliding angle of 2.5° for a 5 μL water droplet. The superhydrophobicity was attributed to a combination of the dual scale roughness at the micro- and nano-meter levels and the low surface energy of the stearic acid coating. This is a simple synthetic methodology requiring no complex or harsh equipment. The copper surface obtained has the excellent non-sticking property, long-term storage stability, and relatively good anti-abrasion property.
