Abstract: Nanoparticles were prepared via chemical precipitation method and the nanocomposites were fabricated using in situ method of polymerization. Both nanoparticles and formulated nanocomposites were characterized using X-Ray Diffraction technique (XRD). From the XRD results, it was observed that the crystallite sizesof the synthesized nanoparticles were calculated using a Debye Scherrer’s equation and were found to be 31.2 nm for NiO nanoparticles, 46.4 nm for BaO nanoparticlesand 32.3 nm for Sb2O3 nanoparticles respectively. These results showed that the sizes of the oxide nanoparticles prepared were within the nanoscale region. Also results from X-ray diffraction of nanocomposites confirmed the presence of nano metal oxides in the polystyrene. Conclusively, it was observed that at high concentration of nanoparticles incorporated in the polystyrene, nanocomposite containing 0.5 g of NiO nanoparticles is more crystalline followed by nanocomposite containing 0.7 g of BaO and nanocomposite containing 1 g of Sb2O3nanoparticles due to more periodicity and preferred crystal orientation. Based on the crystalline nature of the synthesized nanoparticles, it is recommended that during the production of polymer nanocomposites, PS/Sb2O3, PS/BaO and PS/NiO nanocomposites can be used in electrically conductive devices, as reinforcements in construction of buildings, to hinder or slow down the propagation of fire as well as suitable materials for heat transfer applications.
