Abstract
Several kinds of functional particles modified epoxy multilayer composite, which were constituted with lead acrylate/erbium oxide/epoxy and tungsten oxide/erbium oxide/epoxy layer by layer, were successfully prepared. The shielding properties under different γ-ray were tested and discussed in detail. Multilayer composite exhibited higher shielding ability to lower energy γ-ray. The radiation shielding rates of four samples were all above 80% when the energy of γ-ray was about 79.9 keV. The results also revealed that stacking sequence of layer with different functional particles will affect their radiation shielding ability when the energy of γ-ray was low.
