With the increasing industrial oily wastewater and the frequent oil spill accidents, separation of waste oils from oil/water mixture continues to be the hot issue of research. The development of low cost materials with chemically and physically stable properties has become a challenging task for oil/water separation and related applications. Various materials such as sponges, meshes, filter papers, and fabrics have been proposed for oil/water separation. Among them, metal meshes have been considered as the most suitable templates due to their characteristics of low cost, high porosity, and good liquid permeability. However, very toxic chemicals are generally used for oxidation of metal meshes. We report a facile green approach for preparing hierarchically oxidized metal meshes. Subsequently, low surface energy materials are coated on the meshes to induce superhydrophobic property. The resulting meshes exhibited a significant potential for highly efficient oil/water separation. |
