Design and fabrication of a highly efficient, stable and durable new wettability coated stainless steel mesh for oil/water separation

The separation of water-oil mixtures has attracted widespread attention because of the increasing amounts of oily wastewater produced from the daily activities of humans and different industrial processes. Therefore, the development of facile and efficient oil-water separation technologies is imperative. In this work, a new highly superhydrophilic-superoleophobic coated stainless steel mesh was fabricated using virtue of the surface modification of poly (BzVimBr-Vim)@[email protected]2 nanoparticles (NPs) through a facile preparation process. The new fabricated superhydrophilic and highly oleophobic coating exhibits good adhesive properties. The oil contact angle (OCA) and water contact angle (WCA) of the modified stainless-steel mesh were 135° and 0°, respectively. The experimental results indicated that the coated stainless-steel mesh exhibited outstanding separation efficiency for oil/water mixtures.
