摘    要:以铜网为基底,通过浸涂法在其表面制得超疏水超亲油有机-无机复合薄膜,水滴、油滴在其表面的接触角分别为152°和10°。 线性低密度聚乙烯-SiO2纳米球构成的复合阶层结构及低表面能线性低密度聚乙烯涂层的协同作用使铜网产生独特的润湿性。 该铜网具有很好的自清洁性和抗腐蚀性,可用于油水混合物的有效分离。 与传统方法相比,该方法制备超疏水-超亲油薄膜方法简单、成本低、无氟,有望在实践中得到应用。

关 键 词:超疏水  超亲油  线性低密度聚乙烯  SiO2  油水分离

Abstract:An organic-inorganic composite film with superhydrophobicity and superoleophobicity was constructed on copper mesh by facile dip-coating. The water contact angle on the film is 152° while the oil contact angle is less than 10°. It is confirmed that the cooperative effect of the hierarchical structures composed by linear low density polyethylene(LLDPE) and SiO2 nanoballs, and the nature of the LLPDE contribute to the wettability. The film with unique wettability exhibits self-cleaning and good anti-corrosion properties, and can be employed to effectively separate oil from water. Compared with traditional techniques for constructing superhydrophobic-superoleophilic film, the method adopted here is simple, low cost, fluorine-free, and may be applied in practice.
Keywords:superhydrophobicity  superoleophobicity  linear low density polyethylene  SiO2  oil-water separation
