Abstract In this study, isophtalic neopentyl glycol polyester (NPG-PES) based composites with different loading ratios of pure tungsten metal (W), tungsten (VI) oxide (WO3), tungsten boron (WB) and tungsten carbide (WC) composites were prepared as alternative shielding materials for ionizing electromagnetic radiation (IEMR) shielding. Structural characterizations of the composites were done. Gamma spectrometric analysis of composites for 80-2000 keV energy range was performed and their usability as IEMR shielding was discussed. As a result, the produced composites showed a shielding performance of 60-100% of the lead (the most widely used IEMR shielding material) depending on the reinforcement material, reinforcement loading rate and experimental conditions. Thus, it was reported that produced composites could be an alternative to lead shieldings that have several disadvantages as toxic properties, difficulty of processing and inelasticity.

不同钨化合物增强剂对新戊二醇聚酯电磁辐射屏蔽性能的影响

摘要 在本研究中，采用不同负载比的纯金属钨 (W)、氧化钨 (WO3)、硼钨 (WB) 和碳化钨 (WC) 复合材料制备了基于间苯二甲酸新戊二醇聚酯 (NPG-PES) 的复合材料。制备用作电离电磁辐射 (IEMR) 屏蔽的替代屏蔽材料。完成了复合材料的结构表征。对 80-2000 keV 能量范围的复合材料进行了伽马光谱分析，并讨论了它们作为 IEMR 屏蔽的可用性。结果，根据增强材料、增强加载速率和实验条件，生产的复合材料显示出铅（最广泛使用的 IEMR 屏蔽材料）的 60-100% 的屏蔽性能。因此，
