Abstract

Aniline hydrochloride (ANIHCl) polymerization in aqueous phase implies several non-disclosure issues involving polyaniline formation mechanism. New findings emphasized the direct influence between the initial state of the synthesis media (found as a colloidal dispersion) and the polymer formation and structure. The colloidal aggregation occurred by a self-assembling phenomenon (at specific monomer concentrations). This affects the monomer conversions and polymer network structure. This phenomenon was observed by several simple means (refractometry, conductometry, FTIR, UV-VIS, TGA-DTG and SEM analyses). An optimal ANIHCl molar concentration (0.5mol/l) was found for attaining high monomer conversion (over 95%)..
