Microspheres were prepared by complexation of a cationic polymer, polyquaternium-24, and an anionic surfactant, sodium lauryl sulfate (SLS). The cationic polymer solution was emulsified in dimethylsiloxane to give water in silicone emulsion (W/Si), and it was used as a template for the formation of microspheres. The emulsion was dispersed into the SLS solution. In this process, two kinds of droplets, silicone dropletes and microspheres composed of the cationic polymer and SLS, were formed, evidenced by X-ray energy dispersive spectra. The mean diameter of the microspheres was reduced from 105.7 to 64.8 mum as the stirring rate for W/Si preparation increased from 300 to 1000 rpm. It is believed that water droplets in W/Si emulsion, when exposed to SLS solution, could be solidified by the complexation of the cationic polymer and the anionic surfactant.
通过阳离子聚合物聚季铵盐-24与阴离子表面活性剂十二烷基硫酸钠（SLS）的络合制备微球。将阳离子聚合物溶液在二甲基硅氧烷中乳化以得到硅包水乳液（W/Si），并将其用作形成微球的模板。将乳液分散到SLS溶液中。在此过程中，形成了两种液滴，即硅氧烷液滴和由阳离子聚合物与SLS组成的微球，这由X射线能量色散光谱证明。随着制备W/Si时搅拌速率从300 rpm增加到1000 rpm，微球的平均直径从105.7μm减小到64.8μm。据信，W/Si乳液中的水滴在暴露于SLS溶液时，可通过阳离子聚合物与阴离子表面活性剂的络合而固化。
