| 目的 为解决常规发光防伪油墨环境不友好，防伪性能单一等问题，以生物基材料为刚性主体结构，芳香磺酸类化合物为客体分子制备水性生物基室温磷光油墨，探索其性能调控因素及包装防伪应用性能。方法 将生物基材料与芳香磺酸类化合物溶于水中获得室温磷光油墨，调控油墨组分、含量等因素，研究其对油墨黏度、油墨层磷光性能的作用机理，并套印不同发光颜色、余辉时长的防伪油墨，获得多色、动态发光的防伪图案，挖掘其包装防伪应用潜力。结果 实验表明，在水性油墨中，生物基材料添加的质量分数为8%，芳香磺酸类化合物添加量为0.16%时，油墨干燥后获得最佳的长余辉发光效果;使用模板刮涂方式印刷防伪图案，模板厚度为0.5 mm时，防伪图案综合效果最佳。结论 具有丰富氨基、羟基等基团的生物基材料(如羧甲基壳聚糖、海藻酸钠)，能形成具有强氢键作用的刚性结构，有效抑制芳香磺酸类化合物的非辐射跃迁，提升了所制备油墨的发光寿命和效率，有效提升了包装防伪油墨的环境友好度及防伪性能。 |

| The work aims to prepare hydrobiobased room temperature phosphorescent ink with bio-based materials as rigid matrix and aromatic sulfonates as luminescent molecules, to explore its performance control factors and anti-counterfeiting application in packaging, to solve the problem that the conventional luminous anti-counterfeiting ink is not environmental friendly, has single anti-counterfeiting performance. The room temperature phosphorescent ink was obtained by dissolving the bio-based materials and aromatic sulfonates in water. The components and contents of bio-based materials and aromatic sulfonates in the ink were modulated, to study their effects on the ink's viscosity and the afterglow time after printing. Through overprinting a series of luminescent inks with different colors and afterglow time, the colorful anti-counterfeiting patterns with dynamic luminescence were achieved to explore its potential in anti-counterfeiting application. The experiment results demonstrated that, in the water-based ink, when the optimal content of bio-based material was 8% and the optimal content of aromatic sulfonates was 0.16%, the afterglow time was the longest after drying. In stenciling printing, when the thickness of stencil was 0.5 mm, optimal printing performance of the anti-counterfeiting pattern could be acquired. In conclusion, bio-based materials with abundant amino and hydroxyl groups (such as carboxymethyl chitosan and sodium alginate) can form rigid structures with strong hydrogen bonding, effectively inhibit the non-radiative transition of aromatic sulfonic sulfonates, improve the afterglow time and luminous efficiency of the prepared ink, and effectively improve the environmental friendliness and anti-counterfeiting performance of anti-counterfeiting ink for packaging. |
