| 摘 要： | 在有机介质十氢化萘中,以金属钠、硝酸银和油酸钠为起始原料,通过超声辐射使金属钠和硝酸银发生置换反应,成功制备了油酸表面修饰的Ag纳米微粒.采用透射电子显微镜、X射线粉末衍射仪和热分析仪对其形貌、结构和性能进行了表征.透射电镜和X射线粉末衍射研究表明:所制备的油酸表面修饰Ag纳米微粒粒径较小,平均尺寸为10 nm,分布均匀,无团聚现象,且具有面心立方晶型结构.热分析结果表明:所制备的样品含有约9.7%的有机物,并具有良好的热稳定性能.

| Abstract: | The silver nanoparticles modified by oleic acid were successfully synthesized by the replacement reaction of silver nitrate with metal sodium in decalin, and the reaction was achieved via ultrasonic irradiation. The morphology, structure and property of the as-synthesized samples were characterized with TEM, ED, XRD and TG/DTA. The TEM, ED and XRD results show that silver nanoparticles, which possess the same face-centred cubic crystal structure as the bulk silver materials, have an average diameter of 10 nm with a relatively uniform distribution. TG/DTA analyses indicates that the resultant samples contain about 9.7% organic compound with highly thermal stability. |
