摘　　要：由对苯二甲酰氯与不同二胺单体采用界面聚合法制备聚酰胺微胶囊分散染料。用扫描电子显微镜测定微胶囊粒径大小及其分布;紫外-可见分光光度计测定微胶囊中染料扩散到丙酮溶液中的吸光度,确定了微胶囊染料在丙酮中的缓释性能。结果表明,随着脂肪烃基的二胺中亚甲基数的增大,聚酰胺微胶囊分散蓝(2BLN)的粒径和粒径分布变宽,在丙酮中的缓释性增强。Disperse blue 2BLN with polyamide microcapsules was prepared with p-benzoyl chloride and different diamine monomers through interfacial polymerization. The particle size and size distribution of the microcapsules were detected and analyzed by Scanning Electron Microscopy. The release of the dye from the microcapsules into an acetone solution was measured by UV-Vis. It was found that with the increase of the number of the methylene units in the diamine, both the particle size and size distribution increased, and the controlled release performance was improved.
