Abstract
This research aims at the X-ray attenuation effect of Graphene oxide (GO) and lead (∣∣) Oxide (PbO) in epoxy resin (ER). First, GO was synthesized with Hummers’ method, then PbO modified with GO and finally, epoxy-based composites were prepared with various fillers such as GO and PbO/GO with different weight percentages. The composite samples were made in thicknesses of 2, 4, and 6mm. The composites were investigated by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and tensile strength. X-Ray attenuation mass attenuation coefficient were measured when the composites were placed at the distance of 60cm from diagnostic X-rays. The measurements were performed at 20, 40, 60 and 80 kVp. The results indicated that, among all other composites, ER-PbO-GO in 10 wt.% has the best X-Ray shielding property and GO is a suitable candidate for modified metal oxides to attenuation.
