热敏黑可逆热致变色复配物及其微胶囊化研究

摘要

分别选用了二苯甲酮、苯甲酸苯酯和苄基苯基醚作为3组分可逆热致变色复配物的溶剂，选出变色较灵敏、对比度较高的苯甲酸苯酯复配物进行微胶囊包覆。结果表明溶剂与显色剂的作用力强度对热致变色复配物可逆变色性能有很大的影响，而通过微胶囊包覆的方法可以得到稳定性好、变色灵敏程度高、对比度强的可逆热致变色材料。

Abstract：

Benzophenone, phenyl benzoate and benzyl phenyl ether were chosen as solvents of the three-component reversible thermochromic compounds respectively. Phenyl benzoate compound has shown the best performance due to its highest color-changing sensitivity and good contrast. The interaction between solvent and developer were investigated to find its effect on the performance of reversible thermochromic compound. Stable reversible thermochromic material with high color-changing sensitivity and strong contrast has been eventually prepared through microencapsulation.

Keywords： reversible； thermochromic； sensitivity； contrast； microcapsules
