Synthesis of C60-Doped Polyaniline Nanoshuttles

Polyaniline–C60nanoshuttle composites have been successfully synthesized by the oxidative polymerization of aniline with ammonium peroxydisulfate in the presence of C60using an interfacial reaction at room temperature, in which the molar ratio of oxidant to monomer was kept at 0.25:1. The influence of initial C60/aniline molar ratio on the supramolecular structure of the composites was studied. It was found that at low molar ratio (0.01:1) amorphous powders could be synthesized, while the as-synthesized products at the higher molar ratio (0.04:1) were shuttle-like superstructures. FTIR and UV-vis spectroscopy confirmed the presence of C60in the resultant nanocomposite and suggested significant interaction of polyaniline with C60. The evolution of supramolecular structure of polyaniline nanoshuttle–C60nanocomposites was discussed.
