Comparative simulated-data study on the low-energy X-ray shielding performance of micro- and nano-sized Bi2O3-filled PMMA composites
ABSTRACT This work evaluates micro- and nano-sized bismuth oxide fillers in poly(methyl methacrylate) (PMMA) composites for low-energy X-ray shielding. Eleven material formulations were examined: neat PMMA and PMMA/Bi2O3 composites containing 10, 20, 30, 40, or 50 wt% filler in either micro- or nano-sized form. Seven p...
