Abstract The effect of silver ions and silver nanoparticles on the rate of poly-
merization of acrylamide and N-isopropylacylamide was investigated. Composites
of silver particles of diameter around 30 nm and polyacrylamide were prepared by
the photochemical method in the absence of any photosensitizer. The particles
formed were characterized by UV–visible spectrophotometry, XRD, and TEM. It
was shown that the presence of metal ions such as Ag
, and Ni
acrylamide monomer is essential for photoinduced polymerization.

Composite materials based on a dispersion of non-polymeric material in a polymeric
matrix are of growing importance in a wide range of applications. In some cases the
dispersed phase enhances the properties of host polymer and in other cases the
dispersed phase properties are affected [1, 2]. Furthermore, the relationship between
particle structures and catalytic activity and/or selectivity for polymer-entrapped
metal particles has also been studied .
Functionalized metal nanoparticles are also of great interest in terms of their
potential applications in biomedical, electronic, and optical materials [4–10].
Incorporation of nanoparticles in polymer matrices is a ﬁeld of particular interest for
materials engineering and the study of polymer–nanoparticle interactions [11–19].
