Abstract

The invention belongs to the technical field of composite materials, and particularly discloses a super-hydrophobic stainless steel mesh composite material and a preparation method and application thereof.Fe2O3-NCs is evenly loaded on the surface of a stainless steel mesh SSM, surface roughening of the stainless steel mesh is facilitated, and therefore the loading rate and adhesion of a super-hydrophobic component octadecyl trimethoxy silane OTS on the surface of the stainless steel mesh are increased; the super-hydrophobic SSM composite material has super-hydrophobicity and super-lipophilicity, and an oil-water separation test proves that the super-hydrophobic SSM composite material has high oil-water separation efficiency in an oil-water mixture containing toluene, n-octane, gasoline, n-hexane, chloroform, dichloroethane, cyclohexane and corn oil, and is strong in repeated recoverability.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a super-hydrophobic stainless steel mesh composite material and a preparation method and application thereof. Background technique [0002] With the frequent occurrence of pollution incidents such as organic wastewater discharge, chemical leakage and crude oil leakage, the preparation of high-efficiency oil-water separation composites has become a worldwide hot issue. At present, materials such as carbon aerogels, cotton fabrics, foamed carbons and sponges have been widely studied by scholars due to their excellent hydrophobicity and high oil-water separation ability. However, these materials are difficult to be applied on a large scale due to their complex separation process, high preparation cost, secondary pollution or poor recyclability. From the perspective of practical application, it is of great significance to develop a more efficient, simple and ...
