采用细乳化/溶剂蒸发（MESE）的方法，制备了溶剂型染料/聚甲基丙烯酸甲酯（PMMA）复合纳米色素。系统分析了不同实验参数，包括表面活性剂浓度、聚合物浓度、染料装载量及超声时间对所制备的染料/聚合物复合色素形态的影响。结合TEM、X射线光电子能谱（XPS）及元素分析，发现借助MESE法制备染料/PMMA复合色素纳米颗粒具备核壳异质的微观结构。借助紫外-可见分光光度计测试了溶剂型染料经包覆后在水油两相的迁移过程，其随着聚合物溶解所发生的动态变化证实了染料已封装于聚合物壳内。所制备的染料/聚合物复合纳米色素表现出优异的光学稳定性能、存储稳定性能及耐水牢度。

In the present study, the combined mini-emulsion and solvent evaporation (MESE) method was used to prepare solvent dyes/poly (methyl methacrylate) (PMMA) composite nano-colorants. Using dynamic light scattering tests, the effects of the formulation variables, including concentration of surfactant and polymer, dye loading and ultrasonication time, on the size and size distribution of the prepared nanoparticles were examined. Transmission electron microscopy (TEM), XPS and elemental analysis results indicated distinct core-shell structure of SOB/PMMA and SOY/PMMA composite colorant latexes, which proved that dyes were successfully encapsulated in the PMMA matrix using the MESE method. The dynamic migration of encapsulated solvent dyes in water and oil phase was analyzed by UV-visible spectrophotometry, which confirmed the encapsulation of the hydrophobic dyes in PMMA matrix. The resulting composite colorant could be dispersed in water. It also exhibited high light fastness, storage stability and water-fastness.
