Abstract

Recently, attention to polymeric nanocomposites has gained a great extent as they present new opportunities to provide superior properties in microwave absorbing materials. In this study polystyrene (PS) nanocomposites containing various nano-fillers were successfully synthesized and employed as microwave absorbing materials. The mentioned materials are usually designed to solve protection against electromagnetic interference in wireless communication systems and high frequency circuit mechanisms. In this study the performance of three various polystyrene (PS) nanocomposites containing: semi-conductor zinc oxide, non-metallic conductive graphene oxide and magnetic Fe3O4 were compared. The fillers type was selected as variable parameter and its influence on the electromagnetic wave absorption and reflection loss (RL) amount was investigated. The scanning electron microscopy (SEM) was used in morphological and particle size study of the nanocomposites. The electromagnetic wave absorption properties of nanocomposites were studied and compared using a vector network analyzer (frequency range of 5-8 GHz). The results indicate that at the same preparation conditions the polystyrene/graphene oxide nanocomposites have higher absorption compared with others.

轻量化薄型雷达吸波纳米复合材料的优化设计

近年来，聚合物纳米复合材料获得了极大的关注，因为它们为在微波吸收材料中提供优异性能提供了新的机会。本研究成功地合成了含有各种纳米填料的聚苯乙烯（PS）纳米复合材料，并将其用作微波吸收材料。所提到的材料通常被设计用于解决在无线通信系统和高频电路机构中对电磁干扰的保护。在本研究中，比较了三种不同的聚苯乙烯（PS）纳米复合材料的性能：半导体氧化锌、非金属导电氧化石墨烯和磁性Fe3O4。选择填料类型作为可变参数，研究了填料类型对电磁波吸收和反射损耗（RL）量的影响。利用扫描电子显微镜（SEM）对纳米复合材料的形貌和粒度进行了研究。使用矢量网络分析仪（频率范围为5-8GHz）研究并比较了纳米复合材料的电磁波吸收性能。结果表明，在相同的制备条件下，聚苯乙烯/氧化石墨烯纳米复合材料具有较高的吸收性能。
