Abstract In the current study, it was shown that Poly(HEMA-co-Styrene) composites holding tungsten (VI) oxide were formed in groups (10%–50%) by radical polymerization. For this goal, Styrene and HEMA reacted with AIBN for 2.5 h at 65 °C in tetrahydrofuran (THF) to give the consistent polymer. Synthesized Poly(HEMA-co-Styrene) were defined by FTIR, GPC (Mn = 17,100 g/mol PDI = 2.2) and 1H NMR spectroscopy. Poly(HEMA-co-Styrene) -tungsten (VI) oxide composites formed between 80 and 85 °C. The linear attenuation coefficients of the composites were measured by the NaI(Tl) gamma spectrometry system. Attenuation coefficients were also estimated hypothetically by the XCOM platform, taking into account the fundamental analysis of composites and comparing them with empirical outcomes. Consistent with the consequences of SEM analysis, there is a homogeneous distribution among tungsten (VI) oxide units and Poly(HEMA-co-Styrene). Shielding parameters as the tenth value thickness, the half-value thickness, and the mean free path were acquired. Among the composites studied, the best protective material was PS +50% WO3 with lower absorption thicknesses and a higher linear slimming coefficient. Thermal degradation of unirradiated and irradiated polymer composites has also been examined.

聚（甲基丙烯酸羟乙酯-共聚苯乙烯）/氧化钨（VI）复合材料的热和辐射屏蔽性能研究

摘要 目前的研究表明，聚（HEMA-co-Styrene）复合材料含有氧化钨（VI），是通过自由基聚合成组（10%–50%）形成的。为此，苯乙烯和 HEMA 与 AIBN 在 65 °C 下在四氢呋喃 (THF) 中反应 2.5 小时，得到一致的聚合物。合成的聚 (HEMA-co-苯乙烯) 由 FTIR、GPC (Mn = 17,100 g/mol PDI = 2.2) 和 1H NMR 光谱定义。聚（HEMA-co-苯乙烯）-钨 (VI) 氧化物复合材料在 80 至 85 °C 之间形成。复合材料的线性衰减系数由 NaI(Tl) γ 光谱系统测量。XCOM 平台还假设性地估计了衰减系数，同时考虑了复合材料的基本分析并将它们与经验结果进行了比较。与SEM分析的结果一致，钨 (VI) 氧化物单元和聚（HEMA-co-苯乙烯）之间存在均匀分布。获得了作为第十值厚度、半值厚度和平均自由程的屏蔽参数。在所研究的复合材料中，最好的保护材料是 PS + 50% WO3，具有较低的吸收厚度和较高的线性减薄系数。还研究了未辐照和辐照聚合物复合材料的热降解。
