Dynamic contact angle analysis with Wilhelmy＇s plate technique was found to be useful for characterizing the chemical interactions that occur on conducting polymers. The derivatized pyrroles, 3-carboxy-4-methylpyrrole and 3-carbethoxy-4-methylpyrrole, along with pyrrole, were used to prepare polymers with a range of polarities. The predicted trend of polarity, based upon the chemical structures of the polymers, was verified with the technique. It has also been shown that the substrate employed during electropolymerization process plays a major role in determining the properties of the resultant polymer.
