Taking physical vapor deposition of a silver layer as an example, the silver is melted and vaporized by heating with a resistor, a high frequency, or an electron beam in a vacuum environment, and a silver layer is deposited on the back side of the polymer layer 222.
In addition, the cooling layer 22 is disposed in the surface structure 100, so that the cooling layer 22 can be protected, and the service life of the cooling layer 22 can be prolonged. In the present invention, the surface structure 100 is provided with the cooling layer 22 by the in-film decoration technique, so that the surface structure 100 can be cooled by radiation.
According to the preparation method, the cooling layer 22 is arranged under the protective layer 23, so that the cooling layer 22 can be prevented from being damaged, and the service life of the cooling layer 22 is prolonged; meanwhile, the appearance design of the surface structural member 100 is not affected, the application range is wide, and the energy conservation and the environmental protection are realized.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
