Description
Technical Field
The invention belongs to the technical field of self-healing super-hydrophobic materials, and relates to a preparation method of an anti-corrosion self-healing super-hydrophobic material based on reversible hydrogen bonds.
Background
With the discovery of self-healing materials, it is recognized that superhydrophobic coatings capable of healing physical or chemical damage have many potential applications, such as in the fields of self-cleaning, corrosion protection, ice and snow protection, oil-water separation, and the like. The self-healing super-hydrophobic coating mainly comprises a rough micro-nano structure and a low-surface-energy self-healing agent. The micro-nano structure can be prepared by various methods such as electrodeposition, corrosion, photoetching, templates, sol-gel and the like, and has complex process and high requirement on equipment; materials that can be used as self-healing agents are: low surface energy materials such as polydimethylsiloxane, octadecyltriethoxysilane, fluorosilane, etc. Self-healing agents, as a core part of repairing chemically damaged coatings, have been stored in micro-nanostructures by means of chemical bonds, electrostatic interactions and physical storage to date. However, coatings that employ chemical bonds coupled to self healing agents often require additional stimuli, such as temperature, light, humidity, etc., to activate the self healing capabilities of the coating; self-healing agent coatings coupled through electrostatic interaction are generally tedious in preparation process and relatively high in preparation cost; self-healing agents that employ physical storage are often susceptible to evaporation and/or degradation, reducing the coating's ability to be recycled. Until now, reports on hydrogen-bonding-based self-healing coatings have focused on the field of physical structural damage (e.g., cutting, scratching, etc.) of the healing coating, and self-healing techniques of coating surface chemistry and superhydrophobic capability have been left blank after chemical damage has occurred. The self-healing coating based on the reversible hydrogen bonds can be coupled with a large amount of self-healing agents and has a certain protection effect on the self-healing agents, and the self-healing capacity and the recycling stability of the coating are improved. Based on the characteristic that hydrogen bonds are easy to break and reform, after the surface of the material is chemically damaged, the hydrogen bond radical self-healing coating does not need additional stimulation, and rapid, efficient and spontaneous healing can be realized at room temperature.

Detailed Description
The invention is described in detail below with reference to the figures and examples.
Example 1
Adding 10mL of ammonia water into a mixture containing 180mL of ethanol, 20mL of tetraethyl silicate and 20mL of deionized water, stirring for 12 hours at room temperature, and drying at 50 ℃ to obtain silicon dioxide nanoparticles with the particle size of 35 +/-5 nm; adding 1mL of octadecyltriethoxysilane into 70mL of ethanol containing 0.5g of lignocellulose and 6g of prepared silicon dioxide, respectively carrying out ultrasonic and stirring reaction on the suspension at 25 ℃ for 2 hours, washing and purifying the centrifuged particles by ethanol, and drying at room temperature to obtain super-hydrophobic micro/nano particles; adding 3g of super-hydrophobic powder into 80mL of ethanol solution containing 3g of epoxy resin and 2g of polyamide resin, and sequentially carrying out ultrasonic treatment and magnetic stirring for 2 hours respectively to finally obtain the uniform super-hydrophobic coating.
The super-hydrophobic coating is coated on the surface of the metal aluminum in a spraying way, and the spraying process comprises the following steps: spray coating for 30 seconds at a pressure of 1 atm. The coated aluminum substrate was then dried in air at room temperature for 2 hours. Finally, the coated aluminum substrate was further hydrophobically modified by immersing it in an ethanol solution containing 1.0 wt% of octadecyltriethoxysilane for 1 hour. And washing the prepared sample with ethanol to remove unreacted molecules, and then curing and drying at 25 ℃ for 24 hours to finally obtain the anti-corrosion self-healing super-hydrophobic coating with reversible hydrogen bond groups on the surface of the aluminum.
The reversible hydrogen bonds can store a large amount of self-healing agents and have a certain protection effect on the self-healing agents, and the original surface chemical composition and the super-hydrophobicity of the chemically damaged coating can be rapidly recovered at room temperature (4 hours).
Observing the self-healing super-hydrophobic coating prepared on the surface of the aluminum matrix under a scanning electron microscope, the prepared coating has a porous rough structure as shown in figure 1(a), and infrared curves of products prepared in different reaction steps are shown in figure 1 (b). Wherein the infrared curve of the silicon dioxide powder is 3448cm-1The peak is the stretching vibration peak of the hydroxyl group, and the red shift and broadening of the hydroxyl group peak to a low wave number indicate that hydrogen bonds exist in the product. Through testing, the prepared coating has excellent corrosion resistance, as shown in figure 2 (a). When the coating is chemically damaged, only 4 hours are required to restore the original superhydrophobic property at room temperature, as shown in fig. 2 (b).
Example 2
The difference from the embodiment 1 is that:
the coated aluminum substrate was further hydrophobically modified by immersing it in an ethanol solution containing 0.25 wt% of octadecyltriethoxysilane for 1 hour.
Through testing, the prepared coating has excellent self-healing performance, as shown in fig. 3 (a). When the coating is chemically damaged, only 10 hours are required to restore the original superhydrophobic property at room temperature. The superhydrophobic coating prepared under this condition still has a self-healing time much faster than that of the superhydrophobic coating prepared in the form of covalent bonds by curing at a high temperature of 100 ℃ for 2 hours, and as shown in fig. 3(b), the self-healing time of the covalently bonded superhydrophobic coating is about 24 hours at room temperature.
Example 3
The difference from the embodiment 1 is that:
and (3) coating the super-hydrophobic coating on the surface of the fiber fabric in a dipping mode, and curing to prepare the super-hydrophobic fiber fabric with self-healing capability. Wherein, the dipping process comprises the following steps: the fabric was completely immersed in the coating for 1 minute.
Tests prove that the prepared super-hydrophobic fiber fabric has excellent oil-water separation performance, and the oil-water separation capability is reduced after the super-hydrophobic fiber fabric is damaged by oil pollution; after ethanol washing, it took 4 hours to recover the original oil-water separation capacity at room temperature, as shown in fig. 4.
