Abstract

The invention discloses a modified copper foam material and its preparation method and application, belonging to the technical field of superhydrophobic treatment. The preparation method of the modified copper foam material includes the following steps: performing pre-activation treatment on the foam copper, removing the oxide film on the surface of the foam copper, and obtaining the treated foam copper; mixing the growth solution and the treated foam copper, and placing them side by side React at a temperature of 100-140°C to obtain a reaction product; wash and dry the reaction product, then soak it in cetyl mercaptan solution, and then dry the soaked reaction product to obtain the modified product. permanent foam copper material. The modified copper foam material has excellent corrosion resistance, high oil-water separation efficiency, excellent friction resistance and anti-adhesion performance, and it can be used to solve the problems of corrosion, oily wastewater treatment, structure, etc. problems such as frost and icing.

Description

technical field [0001] The invention relates to the technical field of superhydrophobic treatment, in particular to a modified copper foam material and its preparation method and application. Background technique [0002] With the continuous development of science and technology, researchers can achieve oil-water separation by constructing super-hydrophobic surfaces and making them super-lipophilic / super-hydrophobic. In recent years, metal organic framework (Metal organic Framework, MOFs) materials have been widely used in many fields, such as gas separation, sensing, adsorption, catalysis and proton sensing, etc., because MOFs can exhibit excellent microscopic properties on many substrates. Nanoscale surface chemistry, membranes and networks with special wettability based on MOFs have been widely used in the field of oil-water separation. [0003] Among them, HKUST-1 is a typical MOFs material, which has a face-centered cubic structure, nanochannels and adjustable porosity...
