摘　　要：为解决热敏变色材料色谱范围窄、颜色变化单一的问题,以使用原位聚合法得到的热敏变色微胶囊为基础模板,将其分别与制备的红、黄色微胶囊进行拼色实验。通过减法混色原理,不同颜色的微胶囊混合后会呈现出另一种颜色,达到了色谱拓展的目的。借助扫描电子显微镜及红外光谱仪表征了微胶囊的形貌和结构,测试了拼色样品的色差、反射率、K/S值。结果表明:成功制备出了以甲醛-三聚氰胺树脂为壁材、三芳甲烷类基础变色体系为芯材的热敏变色微胶囊;随着外界温度的变化,微胶囊混合体系的颜色也发生显著变化,实现了在不同色调之间的可逆变化,拓展了热敏变色微胶囊的变色色谱范围。In order to address the problems of narrow chromatographic range and limited color of thermosensitive materials,the thermosensitive microcapsules obtained by in-situ polymerization method were used as the basic template for research.They were compared with the prepared red and yellow microcapsules for color-matching experiments.Through the principle of subtractive color mixing,microcapsules of different colors will present another color,fulfilling the purpose of chromatographic expansion.Electron microscopy and infrared spectroscopy results showed that thermosensitive color-changing microcapsules using formaldehyde-melamine resin as the wall material and triarylmethane-based basic color-changing system as the core material were a success.The color difference,reflectance,and K/S values of the color-matched samples were tested,and the results showed that the color of the microcapsule hybrid system also changed significantly with the change of the external temperature,achieving a reversible change between different shades and expanding.
