摘要：

Hollow self-doped polyaniline (SPAN) micro/nanostructures, such as hollow microspheres, aligned pearls, and nanotubes, have been synthesized by a one-step chemical oxidation copolymerization of aniline (AN) and m-aminobenzenesulfonic acid (SAN) using ammonium peroxydisulfate (APS) as the oxidant in aqueous solution. The process is facile and free of any template, surfactant, and external dopants. The shapes and sizes of the hollow SPAN micro/nanostructures can be controlled by adjusting the synthetic parameters, such as the molar ratios of AN and SAN, the concentrations of monomers, and the molar ratios of the monomer and APS. The formation of hollow SPAN micro/nanostructures is possibly related to the self-assembly of SPAN oligomers at the early stage of the copolymerization reaction. The molecular structures of the SPAN micro/nanostructures were determined by FT-IR spectroscopy, which reveales that SO(3)(-) groups are bonded to the aromatic rings in SPAN chains.
