摘要/Abstract

摘要：

运用水热法在铜网表面原位结晶生长苯膦酸锆, 获得微纳米级粗糙结构, 且苯环排列在苯膦酸锆表面的最外层, 使铜网具有超疏水和超亲油的性质, 无需任何低表面能物质修饰, 即可对油水混合物进行分离. 苯膦酸锆层与基底存在一定的结合力, 具有机械稳定性; 同时又具有抗酸碱的化学稳定性. 这种油水分离网不仅能够实现油水混合物的分离, 还可以实现乳化油的油水分离, 在实际生产运用过程中具有较好的应用前景.

Abstract:

In situ crystallized zirconium phenylphosphonate films on the copper mesh using hydrothermal method have superhydrophobic and superhydrophobic properties due to benzene ring being arranged in the outermost layer of zirconium phenyl phosphonate and its micro-nano roughened structure. This material can selectively filter oil from oil/water mixtures without any low-surface-energy material modification. The crystallized zirconium phenylphosphonate films on copper mesh have both mechanical stability and chemical stability. In addition to separation of oil/water mixtures, the copper mesh with ZrPP crystallization are capable of separating surfactant-free oil-in-water and water-in-oil emulsion efficiently, which can be a candidate to be applied in the actual production process.

Key words: Superhydrophobic, Superlipophilic, Oil/water separation, Zirconium phenylphosphonate, Emulsified oil
