Zinc oxide (ZnO) coated superhydrophobic and superoleophilic stainless steel meshes are facilely fabricated chemical immersion growth and subsequent surface modification. The as-prepared meshes show good mechanical durability, chemical stability and corrosion-resistant properties due to a combination of the hierarchical ZnO structure and the low surface energy modification. More importantly, the as-prepared meshes are used for highly efficient separation of various oil/water mixtures. Meanwhile, a new oil skimmer based on the as-prepared mesh is proposed to spontaneously collect floating oil with high separation efficiency and desirable durability.
通过化学浸渍生长和后续表面改性，可轻松制备氧化锌（ZnO）涂层的超疏水超亲油不锈钢网。由于分级ZnO结构和低表面能改性的结合，所制备的网具有良好的机械耐久性、化学稳定性和耐腐蚀性能。更重要的是，所制备的网用于高效分离各种油/水混合物。同时，提出了一种基于所制备网的新型撇油器，以自发收集浮油，具有高分离效率和良好的耐久性。
