Abstract
Polyacrylamide (PAA)–metal nanocomposites were successfully synthesized without blending, at room temperature as follows: a water-absorbent material was used to absorb metal solution (Ag+, Cu+) and then irradiated in the 60Co γ-ray field. The network of the hydrogel prevented the aggregation of silver particles. The products were dried and characterized by X-ray diffiaction (XRD) and transmission electron miscroscopy (TEM). The mechanism of ion reduction is discussed.Keywords
