In the present study, mixed-metal ceramic Fe0.01Al0.5La.0.01Zn0.98O particles and their composites with polyaniline (PANI) were prepared via sol-gel and in situ free-radical polymerization techniques, respectively. Particles and composite formation was confirmed by FT-IR spectroscopy. SEM studies showed the Fe0.01Al0.5La.0.01Zn0.98O particle’s homogeneous dispersion in the polymer matrix. Ceramic particles were found to be in microdimensions. XRD analysis confirmed crystallite size in the range from 22 to 28 nm. Extensive rheological characterization was performed to check the durability of the materials for possible applications. Flow-curve tests suggested that the prepared materials are non-Newtonian (shear thinning) in nature. Increasing temperature have no appreciable effect on the viscosity which confirmed the mechanical stability of the materials. Based on frequency sweep test findings, the mechanical rigidity of the polymer has been enhanced (G′ = 2 × 102−5.22 × 103 Pa) by the introduction of ceramic particles. Conversely, creep compliance has been decreased considerably.
