设计构建了一种用于双重乳液高通量可控构建的三级分裂微流控装置,并深入分析了多级分裂后最终双重乳液的尺寸与单分散性。此外,以油-油-水(O/O/W)双重乳液为模板合成了尺寸均一的核壳型三羟甲基丙烷乙氧基三丙烯酸酯(ETPTA)微囊。相关研究结果可为高度单分散双重乳液及微囊的高通量可控构建提供理论指导。

A three-level splitting microfluidic device is rationally designed and established to realize the controllable construction of high-throughput of double emulsions,and the sizes as well as the mono-dispersity of the resultant double emulsions after multi-stage splitting are also analyzed.Besides,a core-shell ethoxylated trimethylolpropane triacrylate (ETPTA) microcapsules with uniform size are synthesized by using the oil-oil-water (O/O/W) double emulsions as template.The obtained findings in the study can provide theoretical guidance for the controllable construction of high-throughput of double emulsions and microcapsules with high mono-dispersity.
