摘要:
采用水热、刻蚀、高温煅烧以及原位聚合法,制备了聚苯胺(Polyaniline, PANI)修饰蘑菇菌盖状碳(Mushroom cap carbon, MRCC)的复合吸波材料(MRCC@PANI)。通过扫描电子显微镜、透射电子显微镜、红外光谱、X射线光电子能谱对MRCC@PANI复合材料的形貌与结构进行表征,采用矢量网络分析仪分析了PANI的引入对复合材料吸波性能的影响,并探讨了MRCC@PANI复合材料的吸波机理。结果表明:当石蜡介质中MRCC@PANI复合材料的质量分数为30%,且厚度仅为240 mm时,其最大反射损耗可达-4310 dB (958 GHz),对应有效吸波频宽为292 GHz(即反射损耗值低于-1000 dB)。MRCC@PANI复合材料良好的吸波性能主要归因于其阻抗匹配特性、介电损耗和其它协同效应。
