Abstract


Polyaniline (PANI) and PANI/cobalt chloride composites were synthesized by in situ chemical oxidative polymerization of aniline with CoCl2.6H2O using ammonium peroxidisulphate as an oxidant. These composites were characterized by Fourier Transform Infrared (FTIR) Spectroscopy. The FTIR results reveal that some of the bands of CoCl2.6H2O are visible separately in PANI/cobalt chloride composites while some other bands got mixed with PANI. Also there exists small shifting in position of PANI peaks in case of composites. Thus, the FTIR results confirm the presence of cobalt chloride in the composites.


Keywords
