SYNTHESIS AND CHARACTERIZATION OF POLYANILINE AND POLY-ORTHO-METHOXYANILINE. BEHAVIOUR AGAINST CARBON STEEL CORROSION

In the present study the preparation of polyaniline (PANI) and poly-ortho-methoxyaniline (POMA) by chemical method, with different synthesis conditions, has been described. The obtained polymers were characterized by lnfrared and UV-Vis absorption techniques. The morphology of the resulting polymeri...
