Abstract
In order to control the size and shape of Ag nanoparticles obtained by using poly(amidoamine) (PAMAM) dendrimer as template, the complexation between Ag+ ions and dendrimer studied extensively by UVVis spectroscopy and FTIR. After the Ag+/PAMAM demdrimer being reduced by direct chemical reduction, Ag (0) nanoparticles was formed, whose structure and characterization were studied by UV-Vis spectroscopy, transmission electron microscopy (TEM) and electron diffraction (ED) respectively. The results reveal that Ag nanoparticles is a kind of face center cubic crystal and its average size is 4.5 nm. The solubility and stability of the solution containing Ag nanoparticles also indicate that dendrimer is a good kind of template, as well as a protective agent.
