| Abstract | Separation of oil or oily contaminants from water, introduced primarily by various industrial and household applications, is becoming crucial these days to ensure a clean and safe environment. In this study we fabricate a superhydrophobic stainless steel mesh by a one-step electrodeposition technique. The superhydrophobic coating is composed of cerium oxide (CeO2) nanostructures modified with meristic acid, which was characterized by using field-emission scanning electron microscope (FE-SEM) to investigate the morphology of the coating. The water and oil contact angles were measured using an optical contact angle interface tensiometer. Under the optimum conditions, the water contact angle on the coated stainless steel mesh reached up to 150.1 ± 2º which showed superhydrophobcity with sliding angle of 12.6º. The superhydrophobic coated stainless steel mesh showed excellent oil separation efficiency of 98.7% from a mixture of oil in water. |
