摘　　要：本研究探究一种构筑超疏水疏油涂层的简单有效方法。采用全氟十二烷基三氯硅烷(PFDTCS)对羟基多壁碳纳米管进行改性,通过喷涂技术获得水接触角为163.8°、十六烷接触角为139.2°的涂层。通过傅里叶红外光谱(FT-IR)、X射线光电子能谱仪(XPS)和扫描电子显微镜(SEM)对涂层的结构及微观形貌进行表征。结果表明,PFDTCS附着到碳纳米管上,涂层表面具有微纳米多级结构。除了玻璃表面,可在聚合物薄膜及织物上构造出同样的超疏水疏油涂层,并与基底具有良好的粘结力。此外,涂层对粉末及油墨等模型污染物表现出良好的自清洁性能,表明该方法具有良好应用前景。In this paper,a simple and effective method to construct super hydrophobic and oleophobic coating is explored.The hydroxyl multiwalled carbon nanotubes are modified by perfluorodecyltrichlorosilane(PFDTCS),and the coatings with water contact angle about 163.8°and cetane contact angle about 139.4°are obtained by spraying technology.The structure and morphology of the coating are characterized by Fourier transform infrared spectroscopy(FT-IR),X-ray photoelectron spectroscopy(XPS)and scanning electron microscopy(SEM).The results show that PFDTCS is attached to the carbon nanotubes,and there are many micro/nano multi-level structures on the coating surface.In addition to glass surfaces,this method is also suitable for polymer films and textile fabrics,where superhydrophobic and oleophobic coatings can also be constructed.The coating has good adhesion with the substrate.Moreover,the coating also shows good self-cleaning performance to model pollutants such as powder and ink,indicating that the method has good application prospects.
