Recently, polymeric nanoparticles (NPs) have been improved for many applications, such as shielding applications. Pure polyvinyl alcohol (PVA) and polyvinyl alcohol/vanadium pentoxide (PVA/VO) with different weight percentages of VO have been prepared for this purpose. The structure of prepared samples has been characterized by X-ray diffraction (XRD), Attenuated Total Reflectance - Fourier Transform Infrared Spectroscopy (ATR-FTIR), and Transmission Electron Microscope (TEM). The optical band gap, dielectric constant and AC conductivity have been investigated. The studies revealed that the properties of PVA were improved by adding VO except for the sample exceeding 20 wt % due to agglomeration of NPs in the PVA matrix. The mass attenuation coefficient was calculated using both XCOM and Phys-X software. Other radiation protection parameters were also performed using the latest program. It was found that the sample encoded as PVA4 possesses the best shielding properties with the highest VO wt. % among other samples studied in this report. The half-value layers (HVL) values have been compared with two standard radiation shielding glasses (., RS-360 and RS-520) and found to have better shielding capacity.

优化用于屏蔽应用的 PVA/V2O5 的结构、光学和电学性能

最近，聚合物纳米粒子 (NP) 已针对许多应用进行了改进，例如屏蔽应用。为此目的，制备了纯聚乙烯醇（PVA）和具有不同VO重量百分比的聚乙烯醇/五氧化二钒（PVA/VO）。制备的样品的结构已通过X射线衍射(XRD)、衰减全反射-傅里叶变换红外光谱(ATR-FTIR)和透射电子显微镜(TEM)进行了表征。研究了光学带隙、介电常数和交流电导率。研究表明，除了样品中超过 20 wt% 的 VO 外，由于 NP 在 PVA 基质中的团聚，添加 VO 后 PVA 的性能得到了改善。使用 XCOM 和 Phys-X 软件计算质量衰减系数。其他辐射防护参数也使用最新程序进行。结果发现，编码为 PVA4 的样品具有最好的屏蔽性能和最高的 VO wt。占本报告研究的其他样本的百分比。半值层（HVL）值与两种标准辐射屏蔽玻璃（RS-360和RS-520）进行了比较，发现具有更好的屏蔽能力。
