Preparation and Characterization of Platinum/Polyaniline Core-Shell Composite

The core-shell composite of platinum/polyaniline (Pt@PAN) had been prepared by chemical synthesis approach. Reduction of the platinum salt in aqueous solution leaded to the formation of platinum nanoparticles, and then polyaniline were synthesized by interfacial polymerization to get Pt@PAN composite. Transmission electron microscopy of Pt@PAN showed Pt particles are uniform with spherical and granular morphology. Pt@PAN was also characterized by EDAX, XPS and FTIR.
