| titleOfInvention | A technology of acrylic acid-acrylamide copolymer applied to time-resolved information encryption |
| abstract | The invention discloses a technology for applying an acrylic-acrylamide copolymer to time-resolved information encryption. According to the method, acrylic acid, acrylamide, potassium persulfate and ultrapure water are subjected to radical polymerization to obtain acrylic acid-acrylamide copolymer hydrogel, and the solid powder of acrylic acid-acrylamide copolymer is obtained after purification, drying and crushing. Different information is presented in a certain period of time with natural light, 312 nm UV excitation and UV removal, indicating that this technique can be used for time-resolved information encryption. The invention has simple operation, cheap and easily available materials, and the synthesized acrylic acid-acrylamide copolymer can realize the application of time-resolved information encryption technology, and provides an inexpensive solution for information encryption technology and anti-counterfeiting technology. |
