Most organic acid salts exhibit crystallographic polymorphism, and the crystal size can range from tens of nanometers to several microns depending on temperature, concentration, and solvent composition. In this study we present the single organic crystal surface-induced polypyrrole nanostructures. The organic crystal surface-induced polypyrrole nanostructures were synthesized using various organic acid salt crystals in the presence of pyrrole monomer in aqueous medium. Ammonium persulfate and ferric (III) chloride were used as oxidant, and the morphology of the resulting polypyrrole nanostructures were greatly affected by the oxidant types. Wide angle X-ray diffraction (WAXD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analysis were conducted in order to confirm the morphology and formation mechanism of the polypyrrole nanostructures. |
