| titleOfInvention | A recyclable color development method based on metal-polyphenol network structure |
| abstract | The invention relates to a recyclable color development method based on a metal-polyphenol network structure. The method adopts a polyphenol solution to spray or infiltrate a substrate, uses a metal salt solution ink as the color development ink, and the metal salt solution ink and the substrate Contact, form a metal-polyphenol network structure on the substrate in situ and develop color; decolorize the substrate that needs to be decolorized and recovered with an acid solution, after the color development is eliminated, remove the excess acid solution on the substrate to realize the reuse of the substrate. The method can be applied to the fields of writing, spraying, stamping and inkjet printing. The color developing method of the present invention has high stability after color development, high color sharpness and density of the finished product after color development, and can be carried out by using a conventional decolorizing agent. It can quickly decolorize, realize recycling, easy to operate, environmentally friendly, low-cost, efficient, green and reusable. |
