Fine composite particles were prepared with phase inversion chemical pulverization method by use of expanded polystyrene. As the solvent for expanded polystyrene and core material, limonene and a few of dyes were used, respectively.In the experiment, the continuous water phase was poured gradually under agitation into the limonene, where expanded polystyrene and dye were dissolved.With increasing the water phase, first the W/O dispersion was formed and then, the phase inversion occurred to form the O/W dispersion. After this process, limonene was removed by heating under vacuum and fine composite particles were prepared.As a result, it was found that diameters of fine particles were able to be controlled by the agitation speed and the adding speed of water phase in the region from 50nm to 1500nm. Furthermore, the inner structure of fine composite particles was found to be multi core type and to have the channel from the inner to the outer surface of particle.

通过使用膨胀的聚苯乙烯，用相位反转化学粉碎方法制备细胞复合颗粒。 As the solvent for expanded polystyrene and core material, limonene and a few of dyes were used, respectively.In the experiment, the continuous water phase was poured gradually under agitation into the limonene, where expanded polystyrene and dye were dissolved.With increasing the water phase, first the W/O dispersion was formed and then, the phase inversion occurred to form the O/W dispersion.在此过程之后，通过在真空下加热去除去柠檬烯，并准备好细小的复合颗粒。结果，发现细颗粒的直径能够通过搅拌速度和该地区的水相的增加速度控制在50nm到1500nm。此外，发现精细复合颗粒的内部结构是多核心类型，并将通道从粒子的内表面到外表面。
