In this study, we report a general strategy for fabrication of diverse types of conducting PPy micro/nanostructures, using single crystals of organic molecules: 4-sulfobenzoic acid monopotassium salt (4-SBAK), 4-sulfobenzoic acid monosodium salt (4-SBANa), 4-sulfobenzoic acid monolithium salt (4-SBALi), 3-sulfobenzoic acid monosodium salt (3-SBANa), and 2-sulfobenzoic acid monoammonium salt (2-SBANH4) as templates. By using this method, we could produce five different shapes of PPy micro/nanostructures (hexagonal-microplates, curled-nanofibers, lozenge shaped-microplates, rigid-rods, and parallelogram-microplates) determined by the shapes of the organic single crystals in polymerization medium including pyrrole (Py) monomer. Wide angle X-ray diffraction (WAXD), optical microscopy (OM) and scanning electron microscopy (SEM) analysis were conducted in order to confirm the morphology and formation mechanism of the polypyrrole micro/nanostructures. |
