Wetting properties of the 304 stainless steel indicate a hydrophilic nature. In this study, two methods including Cu 2 O thin film coating and chemical etching process have been applied on stainless steel substrates in order to fabricate hydrophobic surfaces. Cu 2 O films were synthesized using spray pyrolysis method at different deposition temperatures and different 2-propanol concentrations. X-ray diffraction (XRD) patterns obtained for the surfaces prepared at different temperatures showed different copper oxide phases well. In addition to XRD results for the samples prepared at different 2-propanol concentrations, the value of optical band gap for these surfaces calculated from UV-Vis spectra confirmed formation of Cu 2 O structure. Statistical parameters of the surfaces were calculated using atomic force microscopy (AFM) data including rms roughness σ , roughness exponent α and correlation length ##IMG## [...] {$\xi .$}

用于疏水性应用的Cu 2 O涂层对不锈钢的改性：形态研究

304不锈钢的润湿性表明其亲水性。在这项研究中，包括Cu 2 O薄膜涂覆和化学刻蚀工艺在内的两种方法已应用于不锈钢基底，以制造疏水表面。采用喷雾热解法在不同的沉积温度和不同的2-丙醇浓度下合成了Cu 2 O薄膜。在不同温度下制备的表面获得的X射线衍射（XRD）图很好地显示了不同的氧化铜相。除了在不同的2-丙醇浓度下制备的样品的XRD结果外，根据UV-Vis光谱计算出的这些表面的光学带隙值也证实了Cu 2 O结构的形成。
