Polypyrrole and polyaniline prepared with cerium(IV) sulfate oxidant

摘要: Abstract The conducting polymers, polypyrrole and polyaniline, were synthesized by chemical oxidative polymerization of the corresponding monomers in 0.1 M sulfuric acid using cerium(IV) sulfate as oxidant at mole ratios oxidant-to-monomer ranging from 0.5 to 3. yields oxidation products determined, samples characterized with respect their elemental composition, molecular structure, morphology. conductivity prepared acid, 10−1 100 S cm−1, was higher compared polyaniline under same conditions, 10−3 10−1 S cm−1. loss mass after deprotonation ammonium hydroxide is reported, discussed terms type protonation also reflected FTIR spectroscopy. bases remained relatively high level, 10−5 10−3 S cm−1, while PANI became non-conducting, 10−12 10−10 S cm−1. polymers had a granular morphology all cases.
