Aspects of the chemical synthesis of PAni-DBSA and its properties

An investigation of the synthesis parameters (i.e., temperature and acid concentrations) in the chemical preparation of PAni-DBSA, was performed. The synthesis temperature was varied from 0 degrees to 40 degrees C, producing a strong effect on both the oxidation states during chain propagation stage and properties of polymers. DBSA molecules are incorporated in the PAni chain. The synthesis temperature has a strong influence on the properties of PAni-DBSA. PAni with a needle-like structure and compact morphology was obtained. The conductivity of polymers is dependent on the benzenoid/quinoid ratio in the polymer chain.
