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Cu2O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Cu2O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 view of the time-consuming procedure and/or high cost for the fabrication of superhydrophobic materials, a simple one-step process was developed to render phosphor-copper mesh surfaces with superhydrophobicity. Thus, coralloid Cu2O nanostructure was generated on phosphor-copper mesh surface by immersing the mesh in the mixed solution (volume ratio of 1:3) of the ethanol solution of 1-dodecanethiol (0.01 mol/L) containing and distilled water at room temperature. The results show that the as-prepared phosphor-copper mesh exhibits very high advancing/receding contact angles of 161.2°±0.7° and 160.2°±0.3°, as well as a low contact angle hysteresis of 1.1°±0.5°. Moreover, four types of oils and organic solvents (gasoline, diesel oil, n-hexane, toluene, and chloroform) can be well separated by the mesh at an efficiency of more than 98%. Compared with the traditional two-step preparation process, the present method has advantages of easy operation, reduced material consumption, short reaction time, and high efficiency. This demonstrates that this approach, being facile, inexpensive and time-saving, can be well adopted to fabricate ordered Cu2O nanostructures on the phosphor-copper mesh, thereby providing some guidances for the large-scale practical application of the superhydrophobic structure.
