采用湿化学法在棉基上制备了超疏水的氧化锌纳米棒阵列薄膜，并在其表面修饰了一层正十二烷基三甲氧基硅烷(DTMS)。用扫描电子显微镜、透射电子显微镜、能谱仪、扫描探针显微镜和X射线光电子能谱对所得棉样进行了表征。通过接触角测量，研究了棉织物样品的润湿性。改性后的棉织物具有超疏水性，8μL水滴的接触角为16 1°，40μL水滴的滚动角为9°。结果表明，合适的表面粗糙度和较低的表面能对形成以Cassie态为主的超疏水表面起重要作用。
A superhydrophobic ZnO nanorod array film on cotton substrate was fabricated via a wet chemical route and subsequent modification with a layer of n-dodecyltrimethoxysilane (DTMS). The as-obtained cotton sample was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), scanning probe microscope (SPM) and X-ray photoelectron spectroscopy (XPS), respectively. The wettability of the cotton fabric sample was also studied by contact angle measurements. The modified cotton fabrics exhibited superhydrophobicity with a contact angle of 161° for 8μL water droplet and a roll-off angle of 9° for 40μL water droplet. It was shown that the proper surface roughness and the lower surface energy both played important roles in creating the superhydrophobic surface, in which the Cassie state dominated.
