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12h,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(11°±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.
