| Abstract: | The flower-like dendrimer and the nanosheet synthesis of polyaniline in the template-free method (rapid mixing) have been done successfully using p-aminoazobenzene (PAAB) and diazoaminobenzene (DAAB) as two new initiators, respectively. In both syntheses, the ammonium peroxydisulfate is used as an oxidant. The effect of initiators on the morphology is demonstrated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images, and the mechanism of nanostructure formation is presented. The polymers are characterized by Fourier transform infrared (FT-IR) and Ultraviolet-visible (UV-vis) spectroscopies and elemental analysis (CHNS). Cyclic voltammetry (CV), electrical conductivity, X-ray diffraction (XRD) and thermogravimetric analysis (TGA) are also presented. Both polymers are semi-crystalline in nature and had the same thermal behavior. [ABSTRACT FROM AUTHOR] |
