Polyaniline/CoNiO2 Nanocomposite: Synthesis, Characterization and Thermal Study

Nano-sized inorganic oxide materials dispersed polymers constitute a special class of composite materials that improve the properties of the base polymer. The way of designing the composite materials by fine dispersion of inorganic nanofillers in polymers leads to special properties and applications. Metal oxide-based polymer nanocomposite materials integrate the science and technology of materials in terms of enhanced properties in comparison with basic materials. A bimetallic oxide material like nanosized cobalt nickelate (CoNiO₂) is considered as an inorganic filler in polyaniline for its composite material. CoNiO₂was synthesized by microwave-assisted route using polyvinyl alcohol (PVA) as a fuel. The in-situ chemical oxidation polymerization method was adopted for the synthesis of nanosized cobalt nickelate dispersed polyaniline nanocomposite (PANI/CoNiO₂) sample. Structural characterization of the derived nanocomposite sample was studie
