The schematic diagram of the self-cleaning glass of one embodiment of the invention is given in Fig. 1.The self-cleaning glass of Fig. 1
Micron concave-convex structure layer 120 including glass body 110 and on the glass body 110 and positioned at micron concaveconvex structure
Low-surface-energy layer 130 on layer 120.
The thickness of micron concave-convex structure layer 120 is preferably 1-8 μm, such as 2,3,4,5,6 or 7 μm, preferably 3-6 microns.
When micron concaveconvex structure 120 is blocked up, increase spraying process, increase production cost, and the light transmittance of visible ray can be reduced.It is described
The thickness of low-surface-energy layer is preferably 50-200nm, for example, 55nm, 60nm, 70nm, 80nm, 100nm, 120nm, 150nm or
180nm。
Micron concave-convex structure layer 120 can be formed by hydrophilic nanoparticles, such as preferably by 2-20nm hydrophilic nanos
Titanium dioxide is formed.Hydrophilic nanoparticles are easily attached to glass surface, and it is recessed can to form micron by methods described below
Male structure layer 120.Hydrophilic nano titanium dioxide is more preferably JR05 titanium dioxide.
The low-surface-energy layer 130 formed in micron concave-convex structure layer 120 can be by 17 fluorine decyl trimethoxy silanes
It is formed, but is more preferably formed by 17 fluorine decyl trimethoxy silanes and stearic acid.Low-surface-energy layer 130 is very thin, and edge
The fluctuating for micron concave-convex structure layer 120 is formed.
Due to foring micron-sized concaveconvex structure on glass body 110, it has been covered on self-cleaning glass micron-sized
Protrusion, moreover, being also covered with relatively smaller protrusion in each protrusion.In addition, it is formd in micron concave-convex structure layer 120
The low-surface-energy layer to rise and fall with concaveconvex structure.Self-cleaning glass of the invention has superpower hydrophobicity, self-cleaning glass as a result,
The contact angle of surface and water may be up to 165 °.There is automatical cleaning ability using camera lens super-hydrophobic made of above-mentioned self-cleaning glass,
After dust is adhered on camera lens, it is easy to be taken away by water droplet.
The SEM figures of the automatically cleaning camera lens of one embodiment of the invention are shown in FIG. 4.SEM figures in Fig. 4 are from from clearly
The photo of the 45 ° of direction shootings in oblique upper of clean camera lens.It can be seen from the figure that in the left side of Fig. 4 is divided into two layers in glass lens,
The SEM electromicroscopic photographs of micron relief structured surface are shown, from the photo it can also be seen that cloth on automatically cleaning camera lens in the figure on right side
Expire and be less than the protrusion for waiting about 5 microns, moreover, being also covered with relatively smaller protrusion in each protrusion, thus formed hydrophobic
Structure.
Another embodiment of the invention provides a kind of picture pick-up device, including above-mentioned automatically cleaning camera lens.The present invention
Automatically cleaning camera lens can be used for various picture pick-up devices.For example, it can be used for the traffic picture pick-up device of road, for field science
The picture pick-up device of research.Common monitoring camera is exposed to outdoor environment for a long time, easily seriously polluted by dust, haze, holds very much
Easily accumulation dust so as to influence the visibility of camera lens, reduces monitoring effect.If these a pair of camera lenses carry out artificial cleaning charge
When it is laborious, greatly increase job costs.And camera lens made of the self-cleaning glass of the present invention is utilized, since camera lens is not easy in itself
Adhering dust, moreover, the dust of adherency thereon is also easy to be taken away by rainwater.
Another embodiment of the invention provides a kind of method for manufacturing self-cleaning glass, including：By hydrophilic nano
The aqueous solution of titanium dioxide is sprayed on formation micron concave-convex structure layer on glass body surface.By 17 fluorine decyl trimethoxy silicon
Drying forms low-surface-energy layer after the aqueous isopropanol of alkane is sprayed in the micron concave-convex structure layer.
In the present invention, the formation of micron concave-convex structure layer and low-surface-energy layer is using spray coating method, without using leaching
Stain method.The thickness of concaveconvex structure is easy to control using spray coating method, in addition, after concaveconvex structure is formed, concavo-convex portion due to
Capillary phenomenon and have bubble, therefore, when forming low-surface-energy layer using infusion process, need to impregnate in the solution for a long time, far
Be not as fast as spray coating method, and thorough impregnation in the solution when, low-surface-energy layer is difficult fully to cover corresponding concaveconvex structure, may
Cause hydrophobicity insufficient.
It is preferable to use JR05 titanium dioxide for hydrophilic nano titanium dioxide, can preferably be attached to glass body table
Face.
In addition, for spraying in micron concave-convex structure layer the 17 fluorine decyl trimethoxies for being used to form low-surface-energy layer
The solution concentration of the aqueous isopropanol of silane can be 0.5-4wt%, preferably 1-2wt%.In addition, it is further preferably wrapped in the solution
Stearic acid is included, 0.5-4g stearic acid can be added in the above-mentioned aqueous isopropanols of every 100g, is preferably added to 1-2g stearic acid.
The thickness of the micron concave-convex structure layer is 1-8 μm, and preferably its thickness is 2-5 μm, the thickness of the low-surface-energy layer
It spends for 50-200nm.
In the method for above-mentioned manufacture self-cleaning glass, before the micron concave-convex structure layer is formed, preferably to glass
