This article is published with open access at Springerlink.com Abstract Polpyrrole PPy Ag nanocomposites were successfully synthesized at the interface of water and ionic liquid by one-step UV-induced polymerization. Highly dispersed PPy Ag nanoparticles were obtained by controlling the experimental conditions. The results of Fourier-transform infrared spectroscopy X-ray diffraction transmission electron microscopy and X-ray photoelectron spectroscopy revealed that the UV-induced interface polymerization leaded to the formation of PPy incorporating silver nanoparticles. It was also found that the electrical conductivity of PPy Ag nanocomposite was about 100 times higher than that of pure PPy. Keywords Polypyrrole Ag Ionic liquid Nanocomposites Introduction Nanocomposites of conducting polymers and metallic nanoparticles have attracted considerable attention in recent years because of their potential applications in various areas such as electrocatalysis chemical sensors Y.
