| 摘 要： | 采用两步法合成了一种非离子型的可聚合乳化剂衣康酸十二醇聚氧乙烯醚-3,并将其与阴离子型衣康酸单十二酯丙基磺酸钠复配应用于细乳液聚合法制备氯菊酯纳米胶囊.采用1H-NMR、FT-IR、TEM等手段对可聚合乳化剂、氯菊酯纳米胶囊结构与形貌进行表征.结果表明:衣康酸聚氧乙烯醚含量占油相的质量百分数为1%;农药和单体比例为1∶1时所得到的纳米胶囊包覆效果最佳.

| Abstract: | Itaconate lauryl alcohol polyoxyethylene(IM),a non-ionic polymerizable emulsifier was synthesized in two steps.It was applied in the nanoencapsulation of permethrin with sodium sulfopropyl-lauryl-itaconate by miniemulsion polymerization.The structure of polymerizable emulsifier was characterized by hydrogen nuclear magnetic resonance spectrum(1H-NMR),fourier transform infrared spectrometer(FT-IR),and the morphology of nanocapsules were analyzed by transmission electron microscope(TEM).The results showed that well-defined capsules could be obtained when the ratio of St/Pt was 1∶1 and emulsifier accounts for 1% percentage of the quality of oil phase. |
