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。 Benzophenone, phenyl benzoate and benzyl phenyl ether were selected as the solvent of the reversible thermochromic compound of the three components respectively, and the phenyl benzoate complex with more sensitive discoloration and higher contrast was selected Microcapsule coating. The results show that the action strength of solvent and developer has a great influence on the reversible discoloration of thermochromic complex, and the method of microcapsule coating can get good stability, high sensitivity to discoloration, high contrast Reversible thermochromic material.
