Abstract

The invention relates to a method for preparing two types of super-hydrophobic membranes simultaneously by utilizing nickel chloride, in particular to a method for preparing a copper myristate membrane with a micro / nano-structure at an anode and a myristic acid membrane embedded with nickel particles at a cathode simultaneously. The method is technically characterized in that: the nickel chloride and myristic acid powder are dispersed in absolute ethanol to form uniform electrolyte, and two copper sheets with 60mm*25mm*1.5mm are taken as electrodes and are electrolyzed under certain direct-current voltage for a certain period of time, so that the copper myristate membrane with the micro / nano-structure is formed at the anode and the myristic acid membrane embedded with the nickel particles is formed at the cathode. The invention provides a simple method for preparing super-hydrophobic membranes at the anode and the cathode simultaneously for the first time; and the super-hydrophobic membranes have good super-hydrophobic performance and have wide application prospect.

Description

technical field [0001] The invention relates to a method for simultaneously preparing two superhydrophobic films by using nickel chloride, in particular to a method for simultaneously preparing a copper myristate film with a micro / nano structure on the anode and a myristate film with nickel particles embedded on the cathode. Background technique [0002] The wettability of solid surfaces is very important in both industrial production and daily life. Inspired by the non-stick properties of biological organisms, the research on biomimetic superphobic materials is being paid more and more attention by researchers. Among them, the most studied is the imitation lotus leaf structure, which is generally composed of a series of micro / nano composite structures and a layer with low surface energy. compound of waxy substances. When a droplet falls on it, the air enclosed in the micro / nanostructure and the protrusions with low surface energy will jointly prop up the droplet. It is ge...
