Detailed Description
The present invention will be described in further detail with reference to the following examples and drawings, which are intended to facilitate the understanding of the present invention and are not intended to limit the present invention in any way.
Example 1:
the scanning electron micrograph of the selected three-dimensional micron/nanometer solid particle copper oxide is shown in figure 1, and the copper oxide is in the micron/nanometer particle shape.
Dispersing the three-dimensional micron/nanometer solid particle copper oxide into ionic liquid, stirring for 60min at 15 ℃, then ultrasonically dispersing for 45min at 65 ℃, vacuumizing in the ultrasonic process to remove air on the interface of the copper oxide and the ionic liquid, and obtaining a mixed material, wherein solid phase particles in the mixed material are uniformly dispersed in a liquid phase and do not agglomerate. The transmission electron micrograph of the mixed material is shown in FIG. 2, which illustrates that the solid phase particles form a cross-linked network structure in the liquid phase after simple dispersion.
And coating the mixed material on a metal substrate to form a film layer. Then, as shown in fig. 3 (a), the film layer is scratched to form a scratch, even if the scratch width reaches a millimeter level, and after 1s, the scratch gradually heals as shown in fig. 3 (b), and after 2s, the scratch is substantially repaired as shown in fig. 3 (c).
The prepared membrane layer is soaked in 1mol/L saline water for 100 hours, and the topography of the membrane layer before and after soaking is shown in figure 4.
The prepared film layer is soaked in 1mol/L hydrochloric acid for 24 hours, and the topography of the film layer before and after soaking is shown in figure 5.
The prepared film layer is soaked in 1mol/L sodium hydroxide for 240 hours, and the topography of the film layer before and after soaking is shown in figure 6.
The prepared film layer is placed in neutral salt spray for corrosion for 240 hours, and the topography of the film layer before and after corrosion is shown in figure 7.
Wherein the bright spots in the left images in fig. 4, 5, 6 and 7 are formed by the reflection of light when the surface concave-convex structure of the film layer is taken; while the absence of bright spots in the right image is due to the sample being photographed in an etching solution at this time.
As can be seen from the morphology photographs before and after the immersion corrosion and the salt spray corrosion in fig. 4, 5, 6, and 7, the metal substrates are corroded to different degrees, and the areas covered by the film layer are not corroded significantly, which indicates that the film layer prepared in the embodiment has not only the ultrafast self-repairing capability but also the excellent corrosion protection capability.
Example 2:
dispersing three-dimensional nano solid particle fullerene into liquid phase material silicone oil, stirring for 30min at normal temperature (25 ℃), then ultrasonically shaking for 60min at 50 ℃, vacuumizing in the ultrasonic process to remove air on the interface of the fullerene and the silicone oil, and obtaining a mixed material, wherein solid phase particles in the mixed material are uniformly dispersed in the liquid phase and do not agglomerate. The transmission electron microscope photo of the mixed material shows that the dispersed solid phase particles form a cross-linked network structure in a liquid phase.
And coating the mixed material on a metal substrate to form a film layer. Then, the film layer is scratched to form a scratch, and even if the width of the scratch reaches a millimeter level, the scratch is basically repaired after 2 seconds, which indicates that the film layer has the ultra-fast self-repairing capability.
Similar to example 1, the film prepared above was immersed in 1mol/L brine for 100 hours, immersed in 1mol/L hydrochloric acid for 24 hours, immersed in 1mol/L sodium hydroxide for 240 hours, and subjected to neutral salt spray corrosion for 240 hours, and it was found that no significant corrosion occurred in the area covered by the film before and after immersion corrosion and salt spray corrosion, indicating that the film had excellent corrosion protection ability.
Example 3:
the preparation method comprises the steps of dispersing three-dimensional micron-sized solid particle zinc oxide into liquid-phase material epoxy resin, oscillating for 45min at normal temperature (25 ℃), then ultrasonically dispersing for 30min at 75 ℃, vacuumizing in the ultrasonic process to remove air on the interface of the zinc oxide and the epoxy resin, and obtaining a mixed material, wherein solid-phase particles in the mixed material are uniformly dispersed in a liquid phase and do not agglomerate. The transmission electron microscope photo of the mixed material shows that the solid phase particles form a close-packed labyrinth structure in the liquid phase after dispersion.
And coating the mixed material on a metal substrate to form a film layer. Then, the film layer is scratched to form a scratch, and even if the width of the scratch reaches a millimeter level, the scratch is basically repaired after about 2 seconds, which indicates that the film layer has the ultra-fast self-repairing capability.
Similar to example 1, the film prepared above was immersed in 1mol/L brine for 100 hours, immersed in 1mol/L hydrochloric acid for 24 hours, immersed in 1mol/L sodium hydroxide for 240 hours, and subjected to neutral salt spray corrosion for 240 hours, and it was found that no significant corrosion occurred in the area covered by the film before and after immersion corrosion and salt spray corrosion, indicating that the film had excellent corrosion protection ability.
Example 4:
dispersing three-dimensional micro/nano solid particle boron nitride into liquid phase material mineral oil, stirring for 15min at 35 ℃, then ultrasonically dispersing for 30min at 80 ℃, vacuumizing in the ultrasonic process to remove air at the interface of the boron nitride and the mineral oil, and obtaining mixed liquid, wherein solid phase particles in the mixed liquid are uniformly dispersed in the liquid phase and do not agglomerate. The solid phase particles in the mixed material are uniformly dispersed in the liquid phase, and agglomeration does not occur. The transmission electron microscope photo of the mixed material shows that the dispersed solid phase particles form a labyrinth structure in the liquid phase.
And coating the mixed material on a metal substrate to form a film layer. Then, the film layer is scratched to form a scratch, and even if the width of the scratch reaches a millimeter level, the scratch is basically repaired after about 2 seconds, which indicates that the film layer has the ultra-fast self-repairing capability.
Similar to example 1, the film prepared above was immersed in 1mol/L brine for 100 hours, immersed in 1mol/L hydrochloric acid for 24 hours, immersed in 1mol/L sodium hydroxide for 240 hours, and subjected to neutral salt spray corrosion for 240 hours, and it was found that no significant corrosion occurred in the area covered by the film before and after immersion corrosion and salt spray corrosion, indicating that the film had excellent corrosion protection ability.
