中文摘要	the combination of electrochemistry with surface plasmon resonance (spr) has been used to characterize the growth of polyaniline (pan) on a gold electrode surface during potential cycling. potential-modulated spr characteristics of the pan film were also revealed. the potential switch between the oxidized and reduced states of pan can lead to a large change of spr response due to the variation in the imaginary part of the dielectric constant of pan film resulting from the transition of the film in conductivity. the redox transition of the pan film during potential cycling is very profitable to the spr measurements. two modes of spr measurement, spr angular scan (r-theta) and the time evolution of the reflectivity change at a fixed angle (r-t), were displayed to study the growth process of the pan film. the angle shift of the resonance minimum recorded at each cathodic limit of cyclic potential scanning allows for the unambiguous measurement of the film growth. during cyclic potential scanning, the r-t curve was repeatedly modulated with the direction of the potential ramp as a result of the redox switch of the pan film, and the amplitude of potential-modulated reflectivity change was well correlated with the cyclic number. the time differential of the r-t curve permits continuous monitoring of the film growth process. these results illustrate that the combined technique is suitable for studying the electropolymerization process of a conducting polymer.
