Synthesis of poly(aniline-co-o-toluidine) nanocolloidal particles in aqueous poly(styrene sulfonic acid) by dispersion polymerization method

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 UVvisible 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.

“…For example, red-blood-celllike polymer particles, with their red-blood-cell-like shape, size and mechanical flexibility, could offer great advantages in terms of in vivo circulation time, in vivo biodistribution and cellular internalization; 7 dimpled particles could delay the release rate of drugs due to their large surface areas and reduce the initial explosion; 8 doughnut-like particles have a higher surface area than the spherical particles, and the dispersion of insertions will experience a lower average distance from the surface. 9 There are many methods to prepare polymer particles, for example, dispersion polymerization, 10,11 emulsion polymerization, 12 spray drying, 13 etc. However, simple and efficient preparation methods are still lacking.…”

Poly(aniline-co-o-toluidine):poly(styrene sulfonic acid) nanocolloidal self assembled multilayer thin films as a hole transport layer in organic solar cells

“…In our earlier work, water dispersible PAT:PSS nanocolloidal particles have been synthesized in the presence of PSS as primary dopant and as well as a stabilizer. The nanocolloidal PAT:PSS particles have been achieved at higher wt% of PSS [26]. However, the ability of an inorganic acid HCl to donate protons is much higher than that of polymeric acid [27][28][29].…”
