Abstract

The invention discloses a preparation method of a superhydrophobic oil-water separation fabric based on chemical copper plating. The preparation method comprises the following steps of treating the fabric with sodium alginate; firstly immersing the fabric in a nickel salt solution for nickel absorption treatment, and then immersing the fabric in a sodium borohydride solution for activation treatment after cleaning the fabric; immersing the fabric in a copper plating solution for copper plating treatment to obtain a copper-plated fabric; and immersing the copper-plated fabric in a corrosive zinc salt solution, and then immersing the copper-plated fabric in a dodecanoic acid ethanol solution after cleaning the copper-plated fabric. A contact angle of the uperhydrophobic oil-water separationfabric prepared by the invention can reach 159 degrees, and the separation efficiency of mixed liquor of dichloromethane and water can reach 99%, and after 60 times, the separation efficiency can still reach 96%.

Description

technical field

[0001] The invention belongs to the technical field of superhydrophobic materials, and in particular relates to a method for preparing a superhydrophobic oil-water separation fabric based on electroless copper plating. Background technique

[0002] In recent years, with the continuous improvement of living standards, a large amount of industrial wastewater and domestic sewage have been produced. In addition, the offshore oil exploitation industry is likely to cause marine pollution incidents such as oil spills, and the oil-polluted water has caused serious damage to the environment. It needs to invest a lot of manpower, material and financial resources, but the effect is minimal. Therefore, how to effectively separate oil and water from oil-contaminated water has received more and more attention. Inspired by superhydrophobic phenomena in nature, such as the lotus leaf effect and rose effect, researchers have used various methods to prepare different types o...
