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.
