Embodiment 1

[0031] 1), take a square stainless steel mesh with a side length of 10cm (the structure of the stainless steel mesh is as follows figure 1 shown), placed in a 250mL beaker. Add acetone to the beaker, and ultrasonically vibrate for 5 minutes using an ultrasonic cleaner. Take out the treated square stainless steel mesh and place it in another clean 250mL beaker, add ethanol with a volume concentration of 75%, and ultrasonically vibrate for 5 minutes with an ultrasonic cleaner. Take out the treated square stainless steel mesh and place it in another clean 250mL beaker, add an appropriate amount of deionized water, and ultrasonically vibrate for 5 minutes with an ultrasonic cleaner.

[0032] 2) Put 51.15 grams of copper chloride (molecular weight: 170.48) and 8 mL of concentrated hydrochloric acid into a 250 mL beaker, then add deionized water, set the volume to 200 mL, and stir with a magnetic stirrer for 20 minutes to form a dark green uniform transparent solution.

Abstract

The invention discloses a bionic oil-water separation membrane based on the oil pollution prevention characteristic of butterfly wings as well as a preparation method and application of the bionic oil-water separation membrane and belongs to the technical field of functional materials. With the inspiration of the oil pollution prevention characteristic of butterfly wings, a morphic synergetic mechanism with a micro-nano structure is applied to a preparation process of an oil-water separation membrane material, and a nanoparticle-coated copper-based porous oil-water separation membrane with a multi-scale hierarchical tree-like structure is prepared by taking a stainless steel mesh as a supportable porous substrate and using a metal chemical deposition and saturated fatty acid crosslinking modification method. The invention provides an oily wastewater separation method which is low in cost and simple in operation. The bionic oil-water separation membrane prepared by using the preparationmethod is higher in oil-water mixture flux, stronger in oil pollution prevention property and wide in application range, can be repeatedly used and can be used for treating industrial oily wastewaterand recycling crude oil leaked on the sea.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a preparation method and application of an oil-water separation membrane with high flux and anti-oil properties. The prepared biomimetic oil-water separation membrane is low in cost, high in stability, reusable, and has certain large-scale industrial application prospects. Background technique [0002] In recent years, the frequent occurrence of offshore oil spill accidents and the wanton discharge of oily sewage in factories have not only caused a huge waste of petrochemical resources, but also brought huge irreversible harm to the environment. The existing oil-water separation membrane materials have their own strengths, and great progress has been made in controlling the preparation cost and improving the efficiency of oil-water separation. However, it is still a major challenge in this field to achieve high-throughput separation of oil-water mixture ...
