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.
