Polyaniline as an electrocatalytic material

The catalytic influence of polyaniline (PANI) film, prepared from sulphuric and perchloric acid solutions, on hydroquinone/benzoquinone (HQ/BQ) and Fe2+/3+ reactions has been investigated. The effect of the PPANI layer thickness on redox reactions has been established, as well as different kinetics depanding on the counter-ion incorporated. The location of the reaction taking place is discussed. Evidence is given for metal- like behaiour of PANI at potentials of emeraldine existence and redox-polymer behaiour at potentials of pernigraniline existence.
