Problems solved by technology

The preparation of porous materials by the hydrogen bubble template method is a simple, convenient, low-cost, and parameter-controllable method. This method can be deposited on copper mesh to obtain a three-dimensional porous network film. The porous film is prepared using dynamic hydrogen bubbles as a template. Compared with the hard template method, the advantage of this method is that it does not need to remove the template, which solves the problems of high cost, complicated operation, serious membrane pollution and other problems of the existing method, and is expected to realize industrial production

Abstract

The invention discloses a preparation method of a super-hydrophobic meshy material. The method comprises the following steps of (1) preparing a porous meshy Cu film by using a hydrogen bubble template method; (2) oxidizing the porous Cu film at a certain temperature to obtain Cu2O, and modifying the surface of the porous meshy Cu film by using dodecylthiol and tetradecanoic acid to obtain a super-hydrophobic porous meshy film. The hydrogen bubble template method for preparing a porous material has the advantages of simplicity, convenience, low cost and parameter controllability; a three-dimensional porous meshy film can be obtained through depositing on a copper wire mesh by using the method; the porous film is prepared by taking a dynamic hydrogen bubble as a template; compared with a hard template method, the method has the advantages that the template is not needed to be removed, the problems such as high cost, complexity in operation and serious film pollution in the traditional method are solved, and the industrial production is expected to be realized.

Description

Technical field [0001] The invention relates to a preparation method of a super-hydrophobic porous network film. Background technique [0002] Oily wastewater is a common wastewater in industry. Direct discharge will cause serious harm to the environment, indirectly pollute the atmosphere and soil, and seriously endanger human health. Oil-water separation technology has an important impact in petrochemical and other fields, including the recovery of sea surface oil, oil production wastewater, and the separation of organic solvents. Since the surface tension between water and oil is generally very different, choosing a surface with different wettability for water and oil can selectively adsorb one of the phases and repel the other, and enhance the wettability of the surface to improve the separation efficiency. [0003] The super-hydrophobic phenomenon generally exists in nature. The main factors affecting its wettability are surface chemical composition and surface microstructure....
