摘　　要：以明胶 阿拉伯树脂为壁材 ,戊二醛作交联剂 ,对热敏变色复配物进行微胶囊包封 ,讨论了复凝聚法制备微胶囊对粒度和结构的影响因素。制备出变色灵敏、颜色变化鲜明、具有较强耐候性的可逆热致变色微胶囊 ,其大小均匀 ,平均粒径为 2 7μm。The thermochromic composite materials were wrapped by the microcapsules with gelatin-acacia as wall-material and glutaraldehyde as crosslinker . The factors influencing the size and structure of microcapsules prepared by complex coacervation were discussed. As a result, the microcapsules, which have thermochromic sensitivity, strong weatherability have been obtained, with average diameter of 27μm.
