Özet

Electropolymerization of pyrrole in the presence and absence of acrylamide was accomplished. Characterization of the soluble and insoluble products was carried out by using UV-visible and FTIR spectroscopy, cyclic voltammetry, colorimetry and four-point probe technique. Role of applied electrical conditions and effect of the presence of acrylamide on the formation of polymers in the solution and on electrode surface were investigated. Conductivity of polypyrrole and poly( pyrrole-acrylamide) free-standing films show a conductivity of 90 and 1.0 S/cm, respectively. Incorporation of the acrylamide to the resulting polymer was supported by electrochemistry, colorimetric and spectroscopic results. The presence of the acrylamide in the resulting polymer affects some of the properties of the polymer film (i.e., color, conductivity, electrochemistry, spectroelectrochemistry, etc.) that may bring some advantages for practical applications.
