Abstract

We have investigated the mechanism of the spontaneous growth of a gold nanoparticle film on a container wall when an aqueous dispersion of gold nanoparticles is shaken with an oil phase containing octadecylamine, as first described by Mayya and Sastry (Mayya, K. S.; Sastry, M. Langmuir 1999, 15, 1902.). Experimental evidence is described, which shows that the film growth is driven by the coalescence of particle-coated emulsion drops with the flat oil-water interface separating the oil and water phases.

摘要

我们研究了在金纳米颗粒的水分散体与含有十八胺的油相混合振荡时，金纳米颗粒膜在容器壁上自发生长的机制，这是Mayya和Sastry首次描述的（Mayya, K. S.; Sastry, M. Langmuir 1999, 15, 1902.）。文中描述了实验证据，表明膜的生长是由颗粒包覆的乳液滴与分隔油相和水相的平坦油水界面合并所驱动的。
