摘要：

Silver nanoparticles (AgNPs) deposited on silica were synthesized by gamma Co-60 irradiation of Ag+ dispersion in silica/ethanol/water mixture (9/80/20:w/v/v). The reduction of Ag+ is occurred by hydrated electron (e(aq)(-)) and hydrogen atom (H-center dot) generated during radiolysis of ethanol/water. The conversion doses (Ag+ -> Ag-0) were determined by UV-Vis spectroscopy. The synthesized AgNPs/silica were characterized by transmission electron microscopy (TEM) and x-ray diffraction (XRD), which showed the size of AgNPs to be in the range of 5-40 nm for Ag+ concentrations from 5 to 20 mM. Masterbatches of PE/AgNPs/silica compound with silver content from 250 to 1000 mg kg(-1) were also prepared. These masterbatches can be suitably used for various applications such as antimicrobial food containers and packing films, etc.
