Embodiment 1

[0021] Prepare 100mL 0.25mol / L CuCl 2 At the same time, the commercial copper foil was washed twice with distilled water, ethanol and distilled water, and then dried in the air. After that, the cleaned copper foil was placed vertically in the above-mentioned solution, soaked for 8 minutes, and then taken out The copper foil is rinsed with deionized water and dried to become the copper foil to be written (named as copper foil A). At the same time, use equipment (such as sewing needles) to puncture a pattern of flowers and "Chinese" characters on another commercial copper foil to obtain a copper foil with graphics (named copper foil B). After that, cover the copper foil B on the copper foil A, and let the CEL-S500 / 350 xenon light source just irradiate the graphic on the copper foil B. After 12 minutes of irradiation, the copper foil B can be displayed on the copper foil A. The pictures and texts on the screen will disappear automatically after being placed in the air atmosphere...

Embodiment 2

[0024] Prepare 100mL 0.40mol / L CuCl 2 Solution, while the commercial copper foil was washed twice with distilled water, ethanol and distilled water successively, and then dried in air. Afterwards, put the cleaned copper foil upright in the above-mentioned prepared solution, soak for 6 minutes, then take out the copper foil, rinse it with deionized water and dry it, and become the copper foil to be written (named as copper foil A). At the same time, use equipment (such as sewing needles) to puncture a flower pattern and "China" characters on another commercial copper foil, and obtain a copper foil with pictures and texts (named copper foil B). After that, cover the copper foil B on the copper foil A, and let the CEL-S500 / 350 xenon light source just irradiate the graphic on the copper foil B. After 18 minutes of irradiation, the copper foil B can be displayed on the copper foil A. The pictures and texts on the screen will disappear automatically after being placed in the air a...

Embodiment 3

[0026] Prepare 100mL 0.25mol / L CuBr 2 Solution, while the commercial copper foil was washed twice with distilled water, ethanol and distilled water successively, and then dried in air. After that, put the cleaned copper foil vertically in the above-mentioned prepared solution, soak for 8 minutes, then take out the copper foil, rinse it with deionized water and dry it to become the copper foil to be written (called copper foil A). At the same time, use equipment (such as sewing needles) to puncture a flower pattern and "Chinese" characters on another commercial copper foil, and obtain a copper foil with pictures and texts (called copper foil B). Afterwards, cover copper foil B on copper foil A, and let the CEL-S500 / 350 xenon light source just irradiate the graphic on copper foil B. After 15 minutes of irradiation, copper foil B can be displayed on copper foil A After placing it in room temperature and air atmosphere for a week, the graphics and texts will disappear automatica...

Abstract

The invention discloses a method for generating pictures and texts by using light to shine on the surface of copper foil. It mainly includes: preparing 100mL of CuCl with a concentration of 0.2-0.5mol / L 2 or CuBr 2 solution. At the same time, the commercial copper foil was cleaned and dried. After that, soak the copper foil in the solution for a period of time, take it out and dry it to obtain copper foil A. At the same time, use equipment to puncture different pictures and texts on another commercial copper foil to obtain copper foil B. Then, cover copper foil B on copper foil A, and let the CEL‑S500 / 350 xenon light source just irradiate the graphic on copper foil B. After irradiating for 10 to 20 minutes, copper foil A can be displayed. Graphic on foil B. After the copper foil A is placed in the air at room temperature for a week, the pictures and texts will disappear automatically, and the pictures and texts will appear again after being illuminated again. The invention has huge commercial value in military stealth materials, anti-counterfeiting marks, microelectronic device modification and the like.

Description

technical field [0001] The invention relates to a method for generating graphics and text on the surface of copper foil, in particular to a method for generating graphics and text on the surface of copper foil by using light, and belongs to the technical field of energy materials. Background technique [0002] Copper foil has good electrical conductivity and flexibility. In lithium-ion batteries, copper foil is often used as the negative electrode collector to transport electrons. In the electrical and electronic industry, copper foil or copper products are widely used in the preparation and production of electronic circuits and circuit boards. Under some specific conditions such as anti-counterfeiting and aesthetics, it is necessary to display patterns or writings on the surface of copper foil for better application. At present, the methods for producing graphics and text on the surface of copper foil are mainly physical methods and chemical methods. Among them, the physi...
