Abstract

Abstract A thorough comparative analysis was conducted between pure epoxy and a novel epoxy composite that included bentonite and WO3 nanoparticles in varying ratios. This study examined five distinct novel epoxy samples (E00, EB0, EBW1, EBW2, and EBW3) to assess their radiation shielding efficiency (RSE), taking into account the addition of bentonite and WO3 nanoparticles. Furthermore, the study compared the RSE of pure epoxy with that of the novel epoxy composite. To evaluate the radiation shielding ability of the studied epoxy samples, a few radiation shielding parameters such as linear attenuation coefficient (LAC), mass attenuation coefficient (MAC), mean free path (MFP), RSE, and transition factor (I/I 0) were calculated. The RSE values of the epoxy samples were E00 (63.41%), EB0 (87.17%), EBW1 (98.26%), EBW2 (99.82%), and EBW3 (99.99%) at an energy of 0.06 MeV with 4 cm thickness. With the increase in the incident energy, the half-value layer and MFP values were increased, whereas the LAC and MAC values decreased. In conclusion, it can be stated that the sample EBW3 is more suitable among the five epoxy samples studied for attenuating the incident photon energy from 0.06 to 1.33 MeV. Noteworthily, the obtained results demonstrate that the addition of WO3 nanoparticles enhances the shielding ability of epoxy when compared to the addition of the same amount of bentonite.

膨润土和WO3纳米粒子对辐射屏蔽用环氧树脂聚合物的亲和力

摘要对纯环氧树脂和一种新型环氧树脂复合材料进行了彻底的比较分析，该复合材料包括不同比例的膨润土和WO3纳米颗粒。本研究检查了五种不同的新型环氧树脂样品（E00、EB0、EBW1、EBW2和EBW3），以评估其辐射屏蔽效率（RSE），同时考虑了膨润土和WO3纳米颗粒的添加。此外，本研究还将纯环氧树脂的RSE与新型环氧树脂复合材料的RSE进行了比较。为了评估所研究的环氧树脂样品的辐射屏蔽能力，计算了一些辐射屏蔽参数，如线性衰减系数（LAC）、质量衰减系数（MAC）、平均自由程（MFP）、RSE和跃迁因子（I/I0）。在0.06的能量下，环氧树脂样品的RSE值为E00（63.41%）、EB0（87.17%）、EBW1（98.26%）、EBW2（99.82%）和EBW3（99.99%） MeV与4 cm厚。随着入射能量的增加，半值层和MFP值增加，而LAC和MAC值降低。总之，可以说，在所研究的五个环氧树脂样品中，样品EBW3更适合将入射光子能量从0.06衰减到1.33 MeV。值得注意的是，所获得的结果表明，与添加相同量的膨润土相比，添加WO3纳米颗粒增强了环氧树脂的屏蔽能力。
