Bismuth oxide-based nanocomposite for high-energy electron radiation shielding
A novel polymer-based nanocomposite was fabricated to investigate its shielding properties against high-energy electron radiation for potential applications in space industry. Bismuth oxide (Bi 2 O 3 ) nanoparticles and multi-walled carbon nanotubes (MWCNT) were added to poly (methyl methacrylate) (...

nanocomposite was 37% lighter in comparison with Al at the same radiation shielding effectiveness in electron energy range of 9–20 MeV. Furthermore, mechanical and thermal properties indicate that PMMA/MWCNT/Bi

can achieve significantly improved tensile strength, initial decomposition temperature, and glass transition temperature over pure PMMA. The stabled thermal properties, chemical structures, and morphology of all materials before and after electron irradiation lead to excellent radiation resistance of PMMA and nanocomposite. In conclusion, the proposed nanocomposite is a promising material for high-energy, electron-beam shielding applications. |
