Synthesis and Electrochemical Properties of Polyaniline Composites

Electrochemical synthesis of polyaniline composites was carried out at electrode potential of 1.00 V from a mixture of aniline and thermally expanded graphite. Surface modification of graphite by aminophenyl groups was performed using 4-nitrobenzenediazonium tetrafluoroborate with subsequent chemical reduction of nitrophenyl groups. Electrochemical properties and surface morphology of the prepared composites were analyzed using cyclic voltammetry and scanning electron microscopy.
