采用化学浴沉积法，以硫代硫酸钠和硫酸铜的混合溶液在铜表面制备了具有微纳二元结构的Cu 2S和Cu 2 O复合膜（Cu2S@Cu2O）。采用廉价的聚二甲基硅氧烷（PDMS）对Cu2S@Cu2O薄膜进行改性，得到了超疏水Cu2S@Cu2O薄膜。所制备的膜显示出优异的拒水性，水接触角大于150。和长期储存稳定性。采用扫描电子显微镜（SEM）、能谱仪（EDS）和衰减全反射傅里叶变换红外光谱（ATR-FTIR）对薄膜的几何形貌和化学成分进行了表征。采用同样的方法制备了超疏水/超亲油铜网，可实现对各种含油污水的分离，分离效率在94%以上。该方法简单、成本低，有望在铜表面大规模制备实用的超疏水Cu2S@Cu2O薄膜。(C)2016年爱思唯尔B。V.保留所有权利。
Cu2S and Cu2O composite (Cu2S@Cu2O) film with micro/nano binary structure was created on copper surface using the mixing solution of sodium thiosulphate and copper sulfate by a facile chemical bath deposition method. After modification with low-cost polydimethylsioxane (PDMS), the superhydrophobic Cu2S@Cu2O film was obtained. The as-prepared film shows outstanding water repellency with a water contact angle larger than 150. and long-term storage stability. The geometric morphology and chemical composition of the film were characterized by scanning electron microscope (SEM), energy dispersive spectrometer (EDS) and attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), respectively. Moreover, the same method was used to fabricate superhydrophobic/superoleophilic copper mesh, and it could realize separation of various oily sewages with separation efficiency above 94%. This strategy has potential to fabricate the practical superhydrophobic Cu2S@Cu2O film on copper surface on a large scale due to its simplicity and low cost. (C) 2016 Elsevier B. V.
