以密胺树脂为壁材,结晶紫内酯为隐色染料的复配物为芯材,利用原位聚合法制备了有机可逆热致变色微胶囊。对制备得到的变色微胶囊的微观形貌结构、粒径分布、热学性能、热致变色性能及其他性能进行了系统测试。结果表明:制备得到的有机可逆变色微胶囊能够满足实际应用的需求。此外,重点讨论了微胶囊的热裂解过程,对颜色变化过程进行了表征。

The organic reversible thermochromic microcapsules were prepared by in-situ polymerization using melamine resin as wall material and crystal violactone as the compound of leuco dye as core material.The microstructures,particle size distribution,thermal properties,thermochromic and other properties of the microcapsules were measured systematically.The test results shown that the microcapsules can meet the requirements of practical application.In addition,the thermal cracking process of the microcapsules was discussed,and characterized the color change process.
