A kind of preparation method of superhydrophobic lipophilic material

Abstract

The invention discloses a superhydrophobic and lipophilic material, which is composed of a matrix, a reinforcing body, a coupling agent and a nano-coating attached to the surface of the matrix. The matrix material is stainless steel mesh, nickel foam, copper foam or titanium foam One, the linking agent is dopamine, the nano-coating on the surface is one or both of hexadecylamine and octadecylamine; the reinforcing body is graphene. Its preparation method is also disclosed; the design concept of the present invention is to coat a layer of reduced graphene oxide on the wire mesh skeleton such as nickel foam, and the graphene as the reinforcement plays a role in improving the strength of the matrix material. The coating uses graphene oxide with a smaller particle size. After reduction, the graphene sheet is thinner, which can exert the excellent performance of graphene. In addition, graphene itself is hydrophobic, and nano-scale low surface energy substances are modified on its surface to realize the combination of the two properties and improve the hydrophobicity and lipophilicity and the durability of use.

Description

technical field [0001] The invention belongs to the field of material preparation, and in particular relates to a preparation method of superhydrophobic and lipophilic materials. Background technique [0002] Superhydrophobic and lipophilic materials have always been a hot topic of theoretical research by researchers. At the same time, their huge potential market prospects are also an important reason why social workers are extremely concerned. With the introduction and emphasis of scientific development theories such as the new century, new energy, and low-carbon environmental protection, the deep improvement and optimization of high-quality, high-efficiency superhydrophobic and lipophilic materials has become an important part of environmental protection. In the process of global industrialization, human beings are very dependent on oil and its derivative products. However, oil spills will inevitably occur during oil extraction and transportation, thereby polluting the env...
