中文摘要:
      目的 制备对水和油具有低浸润性、低粘附性的不锈钢滤网。方法 用FeCl3溶液刻蚀并高温煅烧不锈钢滤网,采用十七氟癸基三甲氧基硅烷对其表面进行改性,制备具有超疏水高疏油表面的不锈钢滤网。分别利用扫描电子显微镜、原子力显微镜和傅里叶变换红外光谱仪对滤网表面的形貌和成分进行分析,用接触角测量仪对表面的润湿性能进行测量,用电化学工作站对试样的耐腐蚀性能进行研究。结果 在不锈钢滤网表面制备出了二元微纳米粗糙结构,对去离子水的接触角达152,滚动角为0.5,对丙三醇的接触达145.2,滚动角为2,对大豆油的接触达140.5,滚动角为8。处理后的不锈钢滤网的电化学参数有明显的改善,缓蚀率达95.6%。结论 制备的超疏水高疏油不锈钢滤网对水和油均具有较低的浸润性及粘附性,且具有更好的耐腐蚀性能。
英文摘要:
      The work aims to prepare stainless steel strainers with low wettability and adhesion to water and oil. Stainless steel strainers with superhydrophobic and high oleophobic surfaces were prepared by etching the strainers with FeCl3 solution, calcining them at high temperature, and modifying the strainer surfaces with (heptafluoro-1,1,2,2-tetrahydrodecyl) trimethoxysilane. Morphology and composition of the strainer surfaces were analyzed with scanning electron microscope, atomic force microscope and Fourier transform infrared spectrometer. Surface wettability was measured with contact angle meter. Corrosion resistance of the samples was studied with electrochemical workstation. Binary micro-nano rough structure was fabricated on the surface of stainless steel strainer. Contact angle with deionized water, glycerol, soybean oil was 152, 145.2 and 140.5, respectively. Rolling angle with deionized water, glycerol, soybean oil was 0.5, 2 and 8, respectively. Electrochemical parameters of the treated stainless steel strainer were significantly improved and inhibition rate reached 95.6%. The superhydrophobic and high oleophobic stainless steel strainer has low wettability and adhesion to water and oil, as well as better corrosion resistance.
