| 總結: | This study investigates the shielding parameters and physical properties of a cerium/nickel/bismuth nanofiller intended for coating applications. Utilizing both green synthesis and modified horizontal vapor phase growth techniques, nickel oxide (NiO) and bismuth oxide (Bi2O3) nanoparticles were synthesized and incorporated into a polymer matrix. Addition of purchased cerium oxide (CeO2) to the fabrication of nanocomposite gave additional synergistic effect among the parameters observed. Synthesized nanoparticles were evaluated using Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX), and X-ray Diffraction (XRD) to investigate the morphological, elemental composition, and crystal structure, respectively. Water contact angle measurements were performed using the Biolin Instrument Tensiometer. The thermal properties, including thermal conductivity and resistance, were evaluated using the GHFM-01 Thermtest. Gamma and electromagnetic interference (EMI) shielding effectiveness were measured, with simulation and experimental values of mass attenuation coefficients compared using XCOM and EpiXS software. The synthesized nanocomposites demonstrated promising radiation shielding capabilities, characterized by favorable mass attenuation coefficients, mean free path, half-value layer, and tenth value layer. The results indicate that the synthesized nanocomposites are viable alternatives to traditional lead-based shielding materials, offering enhanced safety and environmental benefits. |
