On the dynamic-mechanical relaxations of polyaniline(dodecyl benzene sulphonic acid)-complex

Summary form only given. Processibility of polyaniline (PANI) can be improved by using functionalized counter ions, such as dodecyl benzene sulphonic acid (DBSA). In this work we have studied the plasticization efficiency of DBSA by using dynamic mechanical analysis (DIVIA). Compression molded sheets of PANI(DBSA)/sub x/ with varying composition have been investigated. The loss moduli show characteristic peaks according to which the efficiency of plasticization can be determined. Conductivity reaches saturation at approximately x=0.35.
