摘要: Spiral dislocation morphology on the surface of cetyltrimethylammounium bromide (CTAB) crystallites has been discovered for first time. By addition ammonium peroxydisulfate into CTAB crystalline suspension, a drastic change in result is observed from spiral to two dimensional (2D) islands. The and 2D-island structures these could be use as templates synthesis ring-like polypyrrole (PPy) nanowires, respectively, via direct chemical oxidative polymerization pyrrole due oxidation reaction occurring preferentially at steps crystallites. mechanism adsorption oligomers proposed growth PPy nanowires.
