Abstract

The invention discloses a preparation method of a hydrophobic oleophylic material. The preparation method comprises the following steps of (1) carrying out ultrasonic cleaning on a porous copper mesh;(2) preparing copper oxide nanowires through high-temperature oxidation of vacuum equipment; (3) carrying out ion implantation on the surfaces of the nanowires by utilizing a metal ion source; and (4) coating the copper oxide nanowires by utilizing a magnetic filtration deposition technology. Based on high-temperature oxidation, ion implantation and magnetic filtration deposition, a lotus leaf-like super-nano concave-convex structure can be formed by the method. The material prepared by the method has the advantages of a good hydrophobic property, a self-cleaning property and a non-wetting property. Meanwhile, the oil hydrophilic angle is very small. The material has an important application prospect in the aspect of oil-water separation.

Description

technical field [0001] The invention belongs to the field of material preparation, and in particular relates to a method for preparing a hydrophobic and lipophilic material. Background technique [0002] The rapid development of the chemical society will inevitably cause many problems such as a large amount of resource consumption and environmental pollution. Oil-water compounds are one of the common environmental pollutants. According to incomplete statistics, at least 5 million to 10 million tons of oil enter water bodies every year in the world through different ways. In my country alone, about 500 million tons of oilfield produced water needs to be processed every year. On the one hand, its source comes from steel mills, food and catering, garment leather processing plants, petrochemical and metal processing industries, which will produce a large amount of oily wastewater; It not only brings serious environmental pollution problems, but also causes a lot of energy los...
