Polyaniline synthesis with iron(III) chloride-hydrogen peroxide catalyst system: Reaction course and polymer structure study
Original language description
We report on the catalytic polymerization of aniline (ANI) with FeCl(3)/H(2)O(2) system, which can considerably lower contamination of neat polyanilines (PANIs) by side-products characteristic of stoichiometric polymerization. However, catalytically prepared PANIs exhibit reduced conductivity related most probably to side reactions involving radicals generated as integral components of the FeCl(3)/H(2)O(2) system. Catalytic polymerization of ANI with FeCl(3)/H(2)O(2) system was found to be the reactionof approximately 2nd order with respect to ANI and gives PANIs of a good quality only when [H(2)O(2)] in the reaction mixture was kept low, i.e., at under-stoichiometric ratios [H(2)O(2)]/[ANI]. At over-stoichiometric ratio [H(2)O(2)]/[ANI], PANIs of lowered conductivity, worse spectroscopic characteristics and increased size of PANI nanostructures were obtained; nevertheless, these PANIs were not over-oxidized to pernigraniline state.
