Abstract

The invention discloses a preparation method and application of superhydrophobic foam iron. In the invention, firstly, high-entropy alloy is electrodeposited on superhydrophilic foam iron, and then superhydrophobic surface treatment is performed to obtain superhydrophobic foam iron, and then the superhydrophobic foam iron is applied to a designed oil-water separation device for oil-water separation. The invention has simple preparation process, low production cost, greenness and high efficiency, and is suitable for large-scale industrial production. The superhydrophobic iron foam prepared by the invention has the characteristics of self-cleaning, anti-fouling, long-term corrosion resistance, high oil-water separation efficiency and the like, and its static contact angle is greater than 150°, and its rolling angle is less than 10°. The oil-water separation device designed by the invention can realize continuous oil-water separation, is suitable for oil-water separation containing light oil and heavy oil, and has high separation efficiency in the separation process.

Description

technical field [0001] The invention relates to a preparation method and application of superhydrophobic iron foam, and belongs to the technical field of metal surface coating treatment. Background technique [0002] In recent years, the rapid development of the offshore oil industry and the frequent occurrence of oil spill accidents have aroused people's great concern and concern. The risk of oil spills highlights the need to develop simple and effective techniques to remove oil from spill sites. Large-scale oil spills, in addition to the direct threat to marine species and their ecosystems, this disaster and its resulting economic consequences may last for more than a decade. When an oil spill occurs, the oil seal boom is usually used to prevent the spread of oil spills and to carry out subsequent cleaning measures. Examples include oil skimmers, in situ combustion, oil absorbing materials, etc. However, most oil skimmers are inefficient at cleaning and recover mostly a...
