Embodiment 1

[0032] A kind of porous nickel foam with lipophilicity and hydrophobicity is prepared by the following method:

[0033] 1) Clean and dry the oil and impurities on the surface of nickel foam with a size of 100mm*100mm*50mm and a size of 400 mesh;

[0034] 2) dissolving silicone oil and silicone rubber in toluene to obtain a mixed solution; the mass percent of silicone oil in the mixed solution is 10%, and the mass percent of silicone rubber is 0.05%;

[0035] 3) Soak the nickel foam obtained in step 1) completely in the mixed solution prepared in step 2) for 4 hours at a temperature of 30°C;

[0036] 4) The nickel foam soaked in step 3) was taken out and dried, and then dried and cured at 50° C. for 5 hours under air conditions to obtain a nickel foam material with lipophilicity and hydrophobicity.

[0037] The lipophilic and hydrophobic foamed nickel material prepared in Example 1 has a contact angle of 155° to water, a contact angle of 0 to No. 0 diesel oil, and an oil absor...

Abstract

The invention belongs to the field of surface functional modification of materials and particularly relates to a porous metal material having lipophilicity and hydrophobicity and a preparation method of same. The preparation method includes the steps of: soaking a porous metal base material into a mixture liquid prepared from silicon oil, silicon rubber and a solvent, and drying the base material to cure the mixture liquid to prepare the porous metal material having lipophilicity and hydrophobicity, wherein the porous metal base material is a metal fabric material or a metal foam material. The porous metal material has good lipophilicity and hydrophobicity and long service life, has certain strength when being compared with sponge and is higher in permeability than sponge. The preparation method is simple, has short production period, is easy to achieve in industrial production and is prepared from existing industrial products. The porous metal material has stable technology and low cost.

Description

technical field [0001] The invention belongs to the field of material surface functional modification, and in particular relates to a porous metal material with lipophilicity and hydrophobicity and a preparation method thereof. Background technique [0002] Oil-water separation technology plays a very important role in daily life and industrial production. For example, it is widely used in petrochemical, marine oil spill recovery, sewage treatment, catering, chemical distillation and separation, pharmaceutical extraction and separation, etc. Oleophilic and hydrophobic materials are of great significance in the field of oil-water separation. The development of advanced materials can improve the oil-water separation process and equipment, thereby improving the shortcomings of traditional oil-water separation methods such as complex equipment, cumbersome process, and high cost. [0003] At present, the research and development of lipophilic and hydrophobic materials are common ...
