Preparation method of super-hydrophobic oleophylic material

Abstract

The invention discloses a super-hydrophobic oleophylic material which comprises a matrix, a reinforcing body, a coupling agent and a nano coating attached to the surface of the matrix, the matrix material is one of a stainless steel mesh, foamed nickel, foamed copper or foamed titanium, the coupling agent is dopamine, and the nano coating on the surface is one or two of hexadecylamine and octadecylamine; and the reinforcing body is graphene. The invention also discloses a preparation method thereof. According to the design thought, a layer of reduced graphene oxide coats a metal wire mesh framework such as foamed nickel and the like, the graphene serving as the reinforcing body plays a role in improving the strength of the matrix material, graphene oxide with a small particle size is adopted for coating of the graphene, and after reduction, the sheet layer of the graphene is thin, so that the excellent performance of the graphene can be played. In addition, the graphene has hydrophobicity, the surface of the graphene is modified with nanoscale low-surface-energy substances, performance integration of the graphene and the low-surface-energy substances is achieved, and hydrophobicity, lipophilicity and use durability are improved.

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...
