Abstract

The invention relates to a method for preparing an anti-counterfeit label with a micro-nano structure, which is obtained by assembling electrospun fibers and nanoparticles with a core-shell structure. Nanoparticles contain specific Raman molecules with specific Raman fingerprint peaks, the intensity and position of the fingerprint peaks can be converted into specific barcodes. The material can be stably fixed on the glass surface, and the Raman signal remains good after repeated washing, which can be used as an anti-counterfeiting label for glass. The label has a special "topography", that is, micron-scale electrospun fibers and nano-scale core-shell structure, through-hole structure, unique barcode and stable performance.

Description

Technical field

[0001] The present invention relates to a method of preparing a micro-span structure anti-counterfeiting label, belonging to an optical material and its anti-counterfeiting field, particularly suitable for true and false identification of a glass substrate. Background technique

[0002] Car glass is an indispensable part of the car structure. High-quality glass is able to resist the stones of the stones, which is the first barrier to ensure life safety. Counterfeit and shoddy glass not only affects the degree of visual and fatigue, but also makes a serious threat to the lives of the occupant. If the counterfeit and shoddy glass gives a huge profiteering, it will make the consumer's personal, property rights, and seriously restrict the economic development and the image of brand merchants. In order to identify counterfeit and shoddy products, maintain the market order, and the anti-counterfeiting techniques came into being. According to the anti-counterfeit technic...
