IN-SITU CHARACTERIZATION OF CONDUCTING POLYMERS BY MEASURING DYNAMIC CONTACT ANGLES WITH WILHELMYS PLATE TECHNIQUE

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