Abstract

Abstract: In this work, five samples of high-density polyethylene have been made by varying bismuth oxide (Bi2 O3 ) concentration 0.5, 1.0, 1.5 and 2.0 wt%. Scanning electron microscopic (SEM) has been used to analysis of the samples to point out the changes in the surface morphology. Energy Dispersive X-ray (EDX) has been performed for evaluating chemical composition of the prepared samples. X-ray diffraction (XRD) spectra of the pure Bi2 O3, pure high-density polyethylene (HDPE) and HDPE with different amount of Bi2 O3 have been investigated. Additionally, the Raman spectroscopy of all synthesized polymer matrix were measured to explore the different molecular groups. Finally, the mass attenuation coefficients μ/ρ for the samples have been measured using narrow beam of gamma-ray at eight energies between from 30.8 to 383.8 keV. The effect of the photon energy and the addition of Bi2 O3 on the gamma-ray shielding ability of the prepared sample have been discussed. In conclusion, the prepared samples showed good attenuation properties. Highlights: Five high-density polyethylene reinforced by bismuth oxide (Bi2 O3 ) were prepared. SEM has been used to evaluate the changes in the surface morphology. EDX performed for investigating the semi-quantitative for all elements evolved. μ/ρ for has been measured using transmission geometry between 30.8 and 383.8 keV.
