Abstract :
Summary form only given. Electropolymerizations of pyrrole and n-substituted pyrroles, i.e. n-methyl pyrrole and n-ethyl pyrrole on platinum(Pt) electrodes were carried out in two different solution electrolyte systems such as acetonitrile(ACN) solution containing 0.036M tetrabutylammonium dodecylsulfate(TBADs) or aqueous solution containing 0.036M sodium dodecylsulfate(NaDS) under galvanostatic or cyclic conditions. The effects of different electropolymerization methods and different solution electrolyte systems on the electrochemical properties of polypyrrole and poly(N-substituted pyrrole)s were investigated. The conductivities at room temperature of polypyrrole and poly(N-substituted pyrrole)s were measured by the four-point probe method. The time dependences of the thickness of the electropolymerized films prepared by different methods were investigated along with their morphological characteristics using the scanning electron microseope(SEM).
