Fabrication of Superhydrophobic-Superoleophilic Copper Mesh and Its Application in Oil-Water Separation
摘要
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.关键词
