The interaction between the films and the iodine solution was studied using the quartz-crystal microbalance (QCM) technique and the UV–visible absorption spectroscopy. Iodine was found to play multiple roles: the ring-iodination of PANI film, the oxidation of PANI to pernigraniline base, and iodine doping to PANI salt. A sensor based on PANI-coated electrode of QCM was developed to monitor the presence of iodine in solution.
