Wm. Chen et al., Preparation of organic/inorganic nanocomposites with polyacrylamide (PAM) hydrogel by Co-60 gamma irradiation, MATER RES B, 35(5), 2000, pp. 807-812
Polyacrylamide (PAA)-metal nanocomposites were successfully synthesized wit
hout blending, at room temperature as follows: a water-absorbent material w
as used to absorb metal solution (Ag+, Cu+) and then irradiated in the Co-6
0 gamma-ray field. The network of the hydrogel prevented the aggregation of
silver particles. The products were dried and characterized by X-ray diffi
action (XRD) and transmission electron miscroscopy (TEM). The mechanism of
ion reduction is discussed. (C) 2000 Elsevier Science Ltd. All rights reser
