| Abstract: | The conductive polymers with unique nanostructures have attracted intense interest due to their potential application. Here the well-defined polypyrrole nanoflakes (PPy/AS) were fabricated via the facile chemical oxidative polymerization of pyrrole with high feeding ratio of sodium alkane sulfonate (SAS). SAS was used as the surfactant (template) and dopant for the nanostructured conductive polymer for the first time. The morphology of the products changed from particles to nanoflakes with the increasing of the feeding ratio of SAS. The polypyrrole nanoflakes (PPy/AS) were characterized with Fourier transform infrared (FTIR), thermogravimetric analysis (TGA), transmission electron microscopy (TEM) and electrical conductivity techniques. They exhibited the weak electrical conductivity dependence on temperature. |
