In this work, polyaniline-Ag nanocomposite containing modified silane ligand was synthesized via the reduction of AgNO3 with hydrazine on the surface of the emeraldine-base polyaniline containing modified silane ligand. The latter was prepared through chemical polymerization of aniline in the presence of thiol-terminated silane ligand by ammonium peroxydisulfate as an oxidant reagent under ultrasonic waves. Then it was used as a template in the synthesis of Ag NPs. Resultant nanocomposite displayed high dispersity in polar organic solvents and aquous media. Nanocomposite was characterized by UV–Vis and FTIR spectroscopy, X-ray diffraction studies, scanning electron microscopy, energy dispersive analysis of W-ray and transmission electron microscopy. The results confirmed the presence of Ag NPs in nanocomposite and also the successful convertion of emeraldine-salt to emeraldine-base polyaniline. Finally, the electroactivity behavior of initial polymer and resultant nanocomposite was investigated by cyclic voltammetry method.
