以聚乙烯吡咯烷酮(PVP)为壁材,通过单凝聚法制备酞菁酮颜料纳米微胶囊。结果表明,PVP质量、分离剂的加入方式以及搅拌速度等工艺条件对微胶囊粒径和分散性有影响,其中较佳的制备条件为:芯壁比为1.07,分离剂Na_2SO_4按10 m L/min的速度加入,搅拌速度为1 000 r/min。此时,可以制得粒径分布窄,平均粒径小于100 nm的酞菁酮微胶囊,分散体系稳定性良好。 Polyvinylpyrrolidone (PVP) was used as wall material to prepare phthalocyaninone pigment nanocapsules by single-coacervation. The results showed that the quality of PVP, the method of adding the separating agent and the stirring speed had influence on the particle size and dispersibility of the microcapsules. The optimum preparation conditions were as follows: the core-wall ratio was 1.07, the separation agent Na_2SO_4 was 10 m L / min speed, stirring speed of 1 000 r / min. In this case, the phthalocyanine microcapsules with narrow particle size distribution and average particle diameter less than 100 nm can be obtained, and the dispersion system is good in stability.
