| titleOfInvention | Preparation method and application of anti-counterfeiting label based on thermotropic phase change hydrogel |
| abstract | A preparation method and application of an anti-counterfeiting label based on thermotropic phase change hydrogel, wherein the method comprises the steps of: combining two monomers N,N-dimethyl(acrylamidopropyl) ammonium butanesulfonate and acrylamide, Or mix isopropyl acrylamide and acrylamide to obtain a mixed monomer; dissolve the mixed monomer, cross-linking agent, and initiator evenly in water, let stand for more than 30 minutes in a preset temperature environment, and then add a reducing agent and stir evenly A mixed solution is obtained, the crosslinking agent is N,N'-methylenebisacrylamide, the initiator is ammonium persulfate, and the reducing agent is N,N,N',N'-tetramethylethylenediamine; the The obtained mixed solution is transferred to a transparent substrate with groove pattern, and polymerized and coagulated in the pattern area to form a gel, thereby obtaining a thermo-induced phase change hydrogel security label based on the lowest critical solution temperature or the highest critical solution temperature. The anti-counterfeiting label prepared by the invention has higher recognition degree, higher anti-counterfeiting security and stronger encoding ability. |
