CeAlO3 nanoparticle synthesis through combustion-assisted method and structural property assessment in Nano-CeAlO3 polymer composites

Abstract

ABSTRACT This study explores enhancing epoxy polymers with cerium aluminate (CeAlO3) nanoparticles via a solution combustion process. CeAlO3 loading (0.5 to 2.5 wt.%) significantly influences resulting composite properties. Characterization techniques confirm CeAlO3 presence, porous spherical morphology, and formation. FTIR spectroscopy identifies functional groups, while TGA shows excellent thermal stability below 200 °C, with minimal mass loss, and stability at 900 °C. The composites exhibit enhanced properties, with maximum tensile strength at 0.5 wt.%, a linear increase in tensile modulus up to 2.5 wt.%, and maximum compressive strength at 0.5 wt.%, with increasing modulus at higher filler loadings. These findings suggest CeAlO3-filled epoxy composites hold promise for high-temperature applications, emphasizing the importance of low filler concentrations for optimal structural properties. Overall, this research underscores the potential of CeAlO3 nanoparticles in advancing epoxy-based materials across various industries.
