โœฆ Synopsis


Polypyrrole (PPY) films with a thickness of 3-4 m were obtained by chemical oxidation of pyrrole (PY) at the interface of chloroform and water with an oxidant (NH 4 ) 2 S 2 O 8 . The films were compact and could be removed with a solid plate. The quality and compositions of these films varied with the molar ratios of the monomer and oxidant of the reaction systems. Overoxidation of polypyrrole was observed and confirmed by the characterizations via infrared spectra and elemental analysis of the films.
