| Abstract Scope |
Radiation shielding material with enhanced mechanical strength is needed to protect humans and electronics from ionizing X-ray and gamma radiation. Using a patented electrodeposition process, we developed a custom 3D printer filament consisting of bismuth and gadolinium Oxide with different presentations onto Halloysite nanotubes (HNT). Coating effectiveness was evaluated using PDS and EDS data. Mechanical properties were tested through flexural, tensile, and compression strength tests. The test results demonstrate superior properties of Bi2O3 and Gd2O3 (attenuation particles)-coated HNTs. EDX tests confirmed the adhesion of attenuation particles to HNT, while the SEM images showed a surface accumulation. The FTIR spectrum also identified Bi2O3 and Gd2O3 shielding material on HNTs. We 3D-printed a Bi2O3 and Gd2O3/HNT composite (up to 40% Bi2O3 and Gd2O3 deposition). We can also spin nanofibers with these materials suggesting that a composite of nanofibers and 3D printed multilayered construct may be suitable for radiation shielding. |
