Investigation of ternary composites of polyaniline comprising benzalazine and nickel ions and its characterization

Abstract

Recent research works are based on ternary polyaniline composite with nickel oxides, nickel ferrite, cobalt (II), copper (II) doped with graphene, manganese, PVA, carbon and more. Nickel itself being a magnetic material it is much suitable for super capacitive behaviour. Incorporating Nickel (II) chloride and Benzalazine in polyaniline composite will enhance its electromagnetic, electrochemical and mechanical properties. In the present work, ternary composites containing polyaniline, benzalazine and nickel (II) chloride were synthesized by the oxidative polymerization of aniline with different weight percentages of benzalazine and Nickel (II) chloride. Benzalazine gets physically adsorbed on the polymer chain and nickel ions get coordinated in the polymer chain. X-ray diffraction pattern was carried out to determine the crystalline nature of the synthesized samples. The synthesized polymer composites were subjected to the technique of Ultraviolet visible and Fourier transform infrared spectroscopic techniques to find out the optical properties. Surface morphology of the synthesized samples were analyzed using atomic force microscopy and Scanning electron microscopy. Redox behavior and capacitance studies were carried out by using cyclic voltammetry at different solution pH value and the synthesized composites at solution pH value pH 1.0 found to exhibit well defined capacitance behavior.
