We report the use of reverse PS-b-P2VP diblock copolymer micelles as true nanoscale-sized reactor vessels to synthesize ZnO nanoparticles. The reverse micelles were formed in toluene and then sequentially loaded with zinc acetate dihydrate and tetramethylammonium hydroxide reactants. Moreover, high spatial resolution Z-contrast imaging and EDX spectroscopy techniques were used to confirm the segregation of the Zn cation to the core of the loaded micelles. Determining the chemical distribution with high nanoscale spatial resolution is shown to complement the less direct characterization by AFM, DLS and FTIR, thus demonstrating broader implications for the characterization of hybrid nanocomposite systems.
我们报告了使用反 PS-b-P2VP 两亲嵌段共聚物胶束作为真正的纳米级反应容器来合成 ZnO 纳米粒子。反胶束在甲苯中形成，然后顺序加载乙酸锌二水合物和四甲基氢氧化铵反应物。此外，还使用高空间分辨率 Z 对比度成像和 EDX 光谱技术证实了 Zn 阳离子的分离到负载胶束的核心。高纳米空间分辨率确定化学分布被证明可以补充 AFM、DLS 和 FTIR 的较不直接的表征，从而为混合纳米复合材料系统的表征提供了更广泛的意义。
