| titleOfInvention | A kind of preparation method of fast response photochromic gel film material |
| abstract | The present invention relates to a preparation method of a fast-response photochromic gel film material, comprising the following steps: (1) mixing the catalyst aqueous solution and the color developing unit aqueous solution uniformly, adding an alcohol solvent to obtain a catalyst/color developing unit mixed solution; ( 2) Dissolve the polymer material in water to form a mixed solution, heat up to fully swell and dissolve to obtain a polymer material solution; (3) add the catalyst/color developing unit mixed solution to the polymer material solution, and finally add a cross-linking agent to obtain a drop coating (4) Coat the drop coating solution on the substrate by drop coating, and dry it. The prepared gel film material has a fast discoloration speed. Under the stimulation of UV light, the color can be faded in 5-8s. Under the condition of 25 ℃ dark room, the color recovery takes only 15 minutes. Under the stimulation of red light, the color recovery is only 15 minutes. It takes 140s; the material cost is low, the synthesis process is simple, the reversible discoloration efficiency is high, and the cycle life is long. It has great application value in the fields of information storage and anti-counterfeiting. |
