Xf. Qian et al., Preparation and characterization of polyvinylpyrrolidone films containing silver sulfide nanoparticles, J MAT CHEM, 11(10), 2001, pp. 2504-2506
Polyvinylpyrrolidone (PVP)-Ag2S nanocomposites were successfully prepared t
hrough in-situ reaction with CS2 as the sulfur source in ethanol solution a
t room temperature. Transmission electron microscopic (TEM) analysis of the
nanocomposites revealed a raspberry morphology of the inorganic component
with an average particle size of about 8-10 nm and a narrow dispersion. IR
and UV-Vis spectroscopies were used to investigate the reaction process and
the formation of coordination compounds.
