In this work, multiferroic BiNiFeO nanoparticles (NPs) has been fabricated by Sol-gel process, then six nanocomposities (NCs) sheets of PVC/x (BiNiFeO): x = 0.0, 0.5, 1.0, 3.0, 5.0, and 10.0 wt% were produced by means of the solution casting process. The produced sheets coded as pure PVC, PVC/0.5(BiNiFeO), PVC/1.0(BiNiFeO), PVC/3.0(BiNiFeO), PVC/5.0(BiNiFeO), and PVC/10.0(BiNiFeO). X-ray diffraction (XRD), physical, dielectric properties, and γ-ray attenuation capacity have been investigated. The dielectric properties of the investigated NCs sheets were tested at 1 V with a range of frequencies from 50 Hz to 5 MHz. The Phy-X/PSD software used to calculate γ-ray shielding parameters. The density (ρ) of the prepared NCs sheets increased from 1.4051 ± 0.0001 g/cm to 3.2650 ± 0.0001 g/cm. Up to 0.5 wt%, the actual part of permittivity decreased as the concentration of BiNiFeO NPs filler increased, but then increased as filler concentration raised. With an increase in applied field frequency, all prepared NCs sheets exhibited an increase in Ac conductivity. The sample coded as PVC/10.0(BiNiFeO) possessed the highest values of mass-(MAC) and linear-(LAC) absorption coefficients. The half-value-layers (HVLs) decreased as the BiNiFeO NPs content increased in the samples. Correspondingly, (HVL) < (HVL) < (HVL) < (HVL) < (HVL) < (HVL). The effective atomic number (Z) has the same trend of MAC and LAC for all investigated sheets. PVC/10.0(BiNiFeO) sheet possessed the lowest EBF and EABF values among all investigated sheets under study. Results showed that the investigated samples can be used as shields for γ-ray.

掺杂 BiNi0.1Fe0.9O3 纳米钙钛矿的 PVC:制备、物理、介电性能以及 γ 射线吸收和堆积因子

在这项工作中,通过溶胶凝胶工艺制备了多铁性 BiNiFeO 纳米颗粒 (NP),然后制备了六种 PVC/x (BiNiFeO) 纳米复合材料 (NC) 片:x = 0.0、0.5、1.0、3.0、5.0 和 10.0 wt%是通过溶液浇铸工艺生产的。生产的片材编码为纯PVC、PVC/0.5(BiNiFeO)、PVC/1.0(BiNiFeO)、PVC/3.0(BiNiFeO)、PVC/5.0(BiNiFeO)和PVC/10.0(BiNiFeO)。对 X 射线衍射 (XRD)、物理、介电性能和 γ 射线衰减能力进行了研究。所研究的 NC 片材的介电性能在 1 V 电压和 50 Hz 至 5 MHz 频率范围内进行测试。用于计算γ射线屏蔽参数的Phy-X/PSD软件。制备的NC片材的密度(ρ)从1.4051±0.0001g/cm3增加到3.2650±0.0001g/cm3。当 BiNiFeO NPs 填料浓度增加到 0.5 wt% 时,介电常数的实际部分下降,但随后随着填料浓度的增加而增加。随着施加场频率的增加,所有制备的NC片材的Ac电导率均增加。编码为 PVC/10.0(BiNiFeO) 的样品具有最高的质量吸收系数 (MAC) 和线性吸收系数 (LAC)。随着样品中 BiNiFeO 纳米颗粒含量的增加,半值层 (HVL) 减少。相应地,(HVL)<(HVL)<(HVL)<(HVL)<(HVL)<(HVL)。对于所有研究的片材,有效原子序数 (Z) 与 MAC 和 LAC 具有相同的趋势。 PVC/10.0(BiNiFeO) 片材在所有研究片材中具有最低的 EBF 和 EABF 值。结果表明,所研究的样品可以用作γ射线的屏蔽体。
