Abstract

Abstract Nanocolloidal poly(aniline-co- o -toluidine) particles were synthesized by dispersion polymerization using different weight ratios of steric stabilizer poly(styrene sulfonic acid). The dispersed nanocolloidal particles ranging from 10 to 100 nm were inspected by transmission electron microscopy and particle size analyzer. The strong doping level of particles at higher weight ratios of stabilizer was analyzed by elemental analysis. The functional groups of particles were identified by Fourier transform-infrared spectra. A reduction of the conjugation length in the particles leads to the homogeneous mixture of phases which was confirmed by scanning electron microscopy and UV–visible spectra. The blue shift polaron band has confirmed the change in conjugation length of the particle. High thermal stability of particles was examined by thermogravimetry analysis.
