CeO₂ was synthesized by the co-precipitation method on the Cu mesh substrate and modified the surface of CeO₂@Cu mesh by stearic acid (SA). The superhydrophobic behavior was ascribed to the combination of hierarchical micro–nanostructure of CeO₂ and the hydrophobic alkyl groups from SA. The SA-CeO₂@Cu mesh had antiacid and base stability and excellent durability as well as high separation efficiency. The separation efficiency can be up to 98.0% after separating 30 times.

超疏水SA-CeO2@Cu网的制备及其在油水分离中的应用

CeO ₂是通过共沉淀法在 Cu 网片基底上合成的，并用硬脂酸 (SA)对 CeO ₂ @Cu 网片的表面进行改性。超疏水行为归因于CeO ₂的分级微纳米结构和SA 的疏水烷基的组合。SA-CeO ₂ @Cu网具有抗酸碱稳定性和优异的耐久性以及高分离效率。分离30次后分离效率可达98.0%。
