Abstrakt
The oxidative polymerization of aniline was studied in order to determine a favourable
combination of reaction conditions leading to polyaniline (PANI) nano-sized particles of
high aspect ratio and narrow polydispersity. The dimensions and morphology of PANI
particles were tuned by the following reaction conditions: oxidant type, reaction
temperature, reaction time, way of stirring the reaction mixture, and dopant type. The
desired rod-shaped PANI morphology was achieved in the case of aniline oxidative
polymerization carried out at 50 °C for 24 h and at constant stirring with a magnetic unit,
when using (NH4)2S2O8 as the oxidant. The best aspect ratio under the above-mentioned
conditions was reached by using HCl, p-toluenesulphonic acid, and H2SO4; all being used
as dopants.
