【摘要】：针对超疏水材料制备过程耗时、耗力或成本高昂的问题,采用一步法制备了磷铜网基超疏水表面。室温下将磷铜网浸入到十二烷基硫醇乙醇溶液(0.01 mol/L)与蒸馏水的混合溶液(体积比1∶3)中反应12 h,制备了具有规整珊瑚状Cu_2O纳米结构的磷铜网基超疏水表面。结果表明,该表面呈现对水高的前进角(161.2°±0.7°)和后退角(160.2°±0.3°),极低的接触角滞后(1.1°±0.5°)。另外,该疏水性磷铜网对汽油、柴油、正己烷、氯仿4类油和有机物质分离效率均大于98%。对比传统的两步法合成过程,该方法具有操作简单、物料损耗少、反应时间短和效率高等优点。这表明该制备方法简单、廉价、节省时间,能够在磷铜网表面制备出规整的Cu_2O纳米结构,从而为超疏水表面的大规模实际应用提供了借鉴和参考。
[Abstract]:In order to solve the problem that the preparation of superhydrophobic materials is time-consuming, labor-consuming or costly, the superhydrophobic surface based on phosphorous copper mesh was prepared by one-step method. Copper phosphorus mesh was immersed in dodecyl mercaptan ethanol solution (0.01 mol / L) and distilled water (volume ratio 1: 3) at room temperature for 12 h to prepare the superhydrophobic surface of copper phosphorus mesh with regular coral-like Cu2O nanostructure. The results show that the surface exhibits a forward angle (161.2 掳卤0.7 掳) and a receding angle (160.2 掳卤0.3 掳) and a very low contact angle (1.1 掳卤0.5 掳). In addition, the separation efficiency of the hydrophobic copper phosphorus net for gasoline, diesel, n-hexane, chloroform oil and organic matter is more than 98%. Compared with the traditional two-step synthesis process, this method has the advantages of simple operation, less material loss, short reaction time and high efficiency. The results show that the method is simple, cheap and time-saving, and can be used as a reference for the large-scale application of superhydrophobic surface.
