Abstract

Polyvinylpyrrolidone (PVP)–Ag₂S nanocomposites were successfully prepared through in-situ reaction with CS₂ as the sulfur source in ethanol solution at 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.
