| 摘 要： | 利用十八胺/正丁醇/正庚烷/甲酰胺/A gNO3(aq)构成的W/O型微乳液体系,在回流状态下由甲酰胺还原银离子制得了十八胺稳定的憎水性银纳米粒子,并通过UV-V is、TEM和XRD等手段对样品进行了表征.所制十八胺包裹的银纳米颗粒粒径分布较宽,且粒子形成了大、小尺寸的两个集团,在自组装试验中大、小粒子分别位于单层膜的中心和边缘地带.

| Abstract: | The hydrophobic silver nanoparticles protected with octadecylamine were fabricated by using formamide as reducing agent in the octadecylamine/n-butanol/n-heptane/formamide/AgNO_3(aq) W/O microemulsion under the state of refluxing.The samples were characterized and analyzed by ultraviolet visible spectroscopy(UV-Vis),transmission electron microscopy(TEM) and X-ray diffraction(XRD).The octadecylamine-capped silver nanoparticles with a broader size distribution obtained through this method formed two groups of particle size.The larger nanoparticles were in the center of self-assembly monolayer film while the smaller were at the edge of the film. |
