以脂肪酸酯相变材料作为光敏变色材料的溶剂，并以二者为芯材，以密胺树脂为壁材，采用原位聚合法，制备了具有智能光敏变色和相变调温功能的微胶囊材料。以DSC、TGA、激光粒度分析仪、扫描电镜、电脑测色仪等对研究结果行进了表征。结果表明，制备的智能光敏变色相变调温微胶囊成型良好，表面光滑圆润，粒径约为3～4μm，粒径分布集中；智能调温功能明显，升降温相变温度分别为270．和202．℃，熔融相变焓为681．J／g ，凝固相变焓为862．J／g ，具有明显的光敏变色功能。
A microcapsule with intelligent photochromic and energy storage temperature adjustment function has been prepared with melamine‐formaldehyde as wall material via an in situ polymerization method ,and the pho‐tosensitive color material which has been dissolved in phase change materials of fatty acid ester was chosen as the core material .DSC ,TGA ,SEM ,particle size analysis and color measurement were used to characterize the prepared microcapsules .The results indicate that the microcapsules had good formation with smooth and com‐pact spherical surfaces ,and their particle size was centralized in 3‐4μm .Moreover ,the microcapsules exhibited excellent performance on photochromic energy storage and temperature adjustment .The rise and cooling phase transition temperature were found to be 27 0. and 20 2. ℃ ,and the molten phase transition enthalpy and solidifi‐cation phase change enthalpy were calculated to be 68 1. and 86 2. J/g ,respectively .
