    In-situ polymerized polyaniline films. Preparation in solutions of hydrochloric, sulfuric, or phosphoric acid

  • Original language description

    Polyaniline (PANI) was prepared by the oxidative polymerization of aniline hydrochloride and aniline sulfate with ammonium peroxydisulfate in acidic aqueous medium. Aniline was similarly oxidized in solution of phosphoric acid. Thin PANI films are produced at the interfaces with the reaction mixture. The progress of polymerization and the PANI-film formation were monitored in situ by Fourier transform infrared spectroscopy after depositing a droplet of the reaction mixture on a ZnSe crystal. The influences of chloride, sulfate, and phosphate counter-ions on the initiation and progress of aniline polymerization have been analysed.

    In situ polymerované polyanilinové filmy. Příprava v roztoku chlorovodíkové, sírové a fosforečné kyseliny

  • Czech description

    Polyanilin (PANI) byl připraven oxidací anilinu hydrochloridu a anilinu síranu peroxydvojsíranem amonným v kyselém prostředí. Anilin byl podobně oxidován též v roztoku kyseliny fosforečné. Na rozhraní s reakční směsí vznikl tenký PANI film. Průběh polymerace a tvorba PANI filmu byly sledovány in situ pomocí Fourier transform infračervené spektroscopie po kápnutím reakční směsi na ZnSe krystal. Byl studován vliv chloridových, síranových a fosforečných proti-iontů na začátek a průběh polymerace anilinu.
