Synthesis and characterisation of poly (pyrrole-co-isoniazid)

D. Lakshmanan and G. Selvanath

Abstract

Poly (pyrrole-co-isoniazid) was prepared by electrochemical and chemical oxidative polymerization. Homo polymer of pyrrole and copolymer thin films of pyrrole and isoniazid were synthesized by using cyclic voltammetry with 0.1M KCl in acetonitrile medium on the surface of the glassy carbon electrode. The copolymer formation, their electrochemical behaviour were studied. The analogous copolymer was prepared via a chemical oxidative polymerization in 1M HCl in the presence of potassium persulphate as oxidant. The structure of the copolymer was systematically studied by IR, NMR and X-ray powder diffraction (XRD) methods and the surface morphology with SEM analysis.
