TLDR
A molecular mechanism for the oxidation of aniline is proposed in this paper, which explains the specific features of polyaniline oligomerization and polymerization in various acidity ranges.Abstract:
Polyaniline is one of the most important conducting and responsive polymers. A molecular mechanism for the oxidation of aniline is proposed. This mechanism explains the specific features of aniline oligomerization and polymerization in various acidity ranges. The formation of polyaniline precipitates, colloids and thin films is reviewed and discussed on the basis of the chemistry of aniline oxidation. The generation of nanostructures, i.e. granules, nanotubes, nanowires and microspheres, is also considered. Oligomers containing phenazine constitutional units play an important role in self-assembly to form templates. Polyaniline chains then grow from these templates and produce the various individual morphologies. Copyright © 2008 Society of Chemical Industryread more

The oxidation of aniline to produce “polyaniline”: a process yielding many different nanoscale structures
TL;DR: The number of different nano-and micro-scale structures produced from the chemical oxidation of aniline into polyaniline is rivaled by few other organic materials.
Journal ArticleDOI
Biocompatibility of polyaniline
TL;DR: The study confirmed that polyaniline has not induced any sensitization and skin irritation either and cytotoxicity, which was higher for polyAniline hydrochloride compared to polyanILine base and was observed on both cell lines, was caused rather by the reaction by-products and residues than by polyanile itself.
