Green synthesis of polyaniline/clay/iron ternary nanocomposite by the one step solid state intercalation method

摘要: The incorporation of two or more active components into clay layered structure with uniform distribution is expected to facilitate wider applications the material. In this study, nanocomposite composed clay, polyaniline and iron nanoparticles was synthesized by a facile environmentally friendly strategy for first time. Local smectite from Tunisia exchanged Fe3+ then it subjected fine grinding anilinium chloride using mortar grinder mixture has been allowed ageing at ambient air until change color dark green. Both interlayer cations atmospheric oxygen act as oxidant aniline polymerization. addition, presence Fe2+ (the result reduction Fe3+) same time favors formation phase. Electrical dielectric properties have studied spectroscopy impedance. ac conduction shows regime constant dc conductivity low frequencies crossover frequency-dependent type AωS high frequencies. material constant, resulting nanoparticles, indicating its improved ability store electric energy be used capacitor.
