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.

Highlights

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 sensorsIn parallel with the development of the above nanocomposites, the topic of ‘‘green’’ chemistry and chemical processes has been emphasized [13]
We presented a simple and environmentally friendly method to synthesize PPy/Ag nanocomposites at the interface of water and ionic liquid
Conducting polymers with various nanostructures have been synthesized in the biphasic ionic liquid/water system [23]
