With the development of the economy, oil spills and random discharge of industrial oily wastewater occur more and more frequently, which seriously endanger the natural environment and human health. However, the existing treatment methods cannot solve the pollution problem of oily wastewater, so it is necessary to explore convenient, efficient and environmentally friendly treatment methods. In recent years, many researchers paid attentions to the special wettability because of its flexibility and wide application range. In order to solve the problems of complex preparation process, expensive equipment, low separation efficiency and poor reusability of oil-water separation materials, a superhydrophobic/superoleophilic nickel mesh was prepared by hydrothermal method and chemical vapor deposition, to provide a new solution for the treatment of oily wastewater pollution.
