Problems solved by technology

No matter which of the above methods, there is one thing in common: the use of chemical reagents to synthesize, which has the advantage of being easy to manipulate, but the disadvantage is that most of these synthesis methods are low-yield (only suitable for laboratory research on small-area samples), difficult to Achieve low-cost large-scale industrialization promotion

preparation example Construction

[0033] Such as Figure 7 As shown, a method for preparing a hydrophobic or oleophobic micro-nano composite structure of the present invention comprises the following steps:

[0034] Step 1, configuring an antiformin solution with a VF (volume fraction) of 5% to 40%, wherein VF is defined as the volume of the antiformin liquid / (volume of the antiformin liquid+volume of deionized water) ;

[0035] Step 2, put the copper base into the antiformin solution in step 1, and react at room temperature for 0.083 to 30 minutes;

[0036] Step 3. Take out the copper base after step 2, rinse it with deionized water and absolute ethanol successively, and then quickly dry it with a hair dryer at a temperature of 70°C to obtain a one-dimensional nano-bean sprout line structure with copper oxide on the surface and Copper base of copper oxide three-dimensional network structure;

[0037] Step 4, such as Figure 4 As shown in (a), adopt stearic acid solution to directly soak the copper base af...

Embodiment 1

[0043] (1) preparing an antiformin solution with a volume fraction VF of 40% as an oxidizing agent and stirring evenly;

[0044](2) Put the red copper sheet into the antiformin diluent at an angle, and the reaction time at room temperature is 10s.

[0045] (3) After the above reaction is completed, the sample is taken out, rinsed with deionized water and absolute ethanol successively, and dried quickly with a hair dryer at a drying temperature of about 70°C. That is, a copper oxide micro-nano composite morphology with a one-dimensional line structure is obtained on the copper surface (morphology such as image 3 As shown in (b), the diffraction effect is as figure 2 (b)).

[0046] (4) Dissolve stearic acid solid powder in absolute ethanol, and ultrasonically oscillate until completely dissolved, and the concentration of stearic acid is 0.03mol / L. Place the red copper sheet after (3) obliquely in the ethanol solution of stearic acid for 15 minutes, remove the red copper she...

Embodiment 2

[0049] (1) Prepare an antiformin solution with a volume fraction VF of 40% as an oxidizing agent and stir evenly.

[0050] (2) Put the red copper sheet into the antiformin diluent at an angle, and the reaction time is 1 min at room temperature.

[0051] (3) After the above reaction is completed, the sample is taken out, rinsed with deionized water and absolute ethanol successively, and dried quickly with a hair dryer at a drying temperature of about 70°C. That is, a copper oxide micro-nano composite morphology with a three-dimensional network structure is obtained on the copper surface (morphology such as image 3 As shown in (c), the diffraction effect is as figure 2 (b)).

[0052] (4) Dissolve stearic acid solid powder in absolute ethanol, and ultrasonically oscillate until completely dissolved, and the concentration of stearic acid is 0.03mol / L. Place the oxidized copper sheet obliquely in the ethanol solution of stearic acid for 15 minutes, remove the copper sheet, was...

Description

technical field [0001] The invention relates to the technical field of nanocomposite materials, in particular to a hydrophobic or oleophobic micro-nano composite structure and a preparation method thereof. Background technique [0002] Copper is widely used, and it is only lower than aluminum in the consumption of non-ferrous metal materials in my country. It is widely used in the fields of electronics, energy transportation, petrochemical industry, machinery and heavy industry. Due to its good mechanical flexibility, excellent electrical conductivity and thermal conductivity, copper and Its alloy has the importance that other metals cannot replace at present. The research on its surface wettability is an indirect research on its anti-corrosion, self-cleaning, drag reduction and other properties. The so-called surface wettability means whether the surface is hydrophobic or oleophobic. Therefore, in order to study corrosion resistance, For copper products with excellent pro...
