Nanocomposites containing metal nanoparticles, dispersed in electrically conducting
polymers such as polyaniline, show enhanced sensing, electrical and catalytic properties
as compared with those of neat polymer. These composites have generated increasing
interest as advanced technological materials due to synergistic effects of both
components. Here, we report silver/polyaniline (Ag/PANI) nanocomposites obtained
through a two-phase water/toluene interfacial reaction. As prepared silver nanoparticles
in toluene with oleylamine as a reducing and stabilizing agent, were used as nucleation
centers for the polymerization of aniline. Once the polymerization occurs at the
interface of the organic (containing the aniline and the silver nanoparticles) and aqueous
(containing the oxidizing ammonium persulfate agent) phase, the polymer grows around
the silver nanoparticles and forming the nanocomposite structure. The formation of
Ag/PANI nanocomposite was characterized by UV–Vis and F...TIR spectroscopy, and
transmission electron microscopy. In contrast to pure PANI, the absorption spectrum of
Ag/PANI nanocomposite showed additional strong band assigned to surface plasmon
resonance absorption of the electrons in the conducting silver bands.
