Ag@SiO 2 @polypyrrole (PPy) nanocomposites were fabricated by a simple method. Ag@PPy yolk–shell nanocomposite was obtained after the removal of the midlayer SiO 2 . TEM confirmed that the movable Ag cores were encapsulated in the interior of the hollow PPy nanoparticles. The structure of the resultant product was characterized by the Raman spectrum and X-ray diffraction technologies...
The cross-linked Ag–AgCl/polypyrrole (PPy) nanocomposite was synthesized using silver nanowires as templates. In the process, FeCl 3 served not only as the oxidant for pyrrole monomer but also as the etching-agent for silver nanowires. The morphologies of the product were observed by transmission electron microscopy. The existence of silver chloride and silver in PPy matrix was confirmed by...
