摘要
该文利用自组装技术,在HNO3(质量分数6.5%)刻蚀的铜表面制备了(3-巯基丙基)三甲氧基硅烷(MPTS)与正辛基三乙氧基硅烷(OS)的复合纳米薄膜,并通过红外光谱对膜结构进行了分析。通过扫描电子显微镜确定了该复合膜具有纳米-微米级粗糙结构;静态接触角达158.6°,滚动角为3°,表明该膜具有超疏水性能;盐水实验证明该复合膜有效地提高了铜的耐腐蚀能力。
In this paper,the composite self-assembled super-hydrophobic nano-film was prepared on the copper surface with(3-mercaptopropyl)trimethoxysilane(MPTS) and octyltriethoxysilane(OS).The copper surface was etched in the HNO3(mass fraction 6.5%) solution before being coated.The structure of the composite film was analyzed by Fourier transform infrared spectra.The scanning electronic microscopy(SEM) indicated that the film had the nano-micro scale structure.The contact angle reached 158.6° with the sliding angle 3° which suggested that the film was super-hydrophobic.The result of the salt solution immersion test showed that the anti-corrosion property of copper surface was greatly improved.
