辉光放电电解等离子体处理制备铁基表面超疏水材料
摘要:
利用辉光放电电解等离子体技术对铁基底表面进行活化,经硬脂酸修饰,得到铁基底超疏水性材料。考察了放电电压、放电时间、Na2SO4浓度以及硬脂酸乙醇溶液浓度对铁基超疏水表面性能的影响。用接触角仪、X射线光电子能谱、红外光谱和扫描电子显微镜测试技术对铁表面的浸润性、表面元素组成结构以及表面形貌进行了表征和分析。结果表明,经修饰的铁基底表面具有良好的疏水性,其水接触角高达154°,滚动角小于5°,且具有良好的稳定性。

Fabrication of Superhydrophobic Iron-surface by Using Glow Discharge Electrolysis Plasma
Abstract:
An oxidation technology,glow-discharge electrolysis plasma,has been successfully used to graft stearic acid onto iron-substrate for the fabrication of superhydrophobic iron-surface.To optimize the fabrication conditions,several important parameters such as the discharge voltage,the discharge time,the concentrations of supporting electrolyte and stearic acid ethanol solution were examined systematically.The wettability,structure and resultant composition of iron substrate were characterized by contact goniometer,X-ray photoelectron spectroscopy(XPS),Fourier transform infrared spectroscopy(FTIR) and SEM.Under the optimized conditions,the contact angle(CA) for the modified iron-substrate surfaces is up to 154° and the sliding angle(SA) is less than 5°.
