摘要：采用酞菁铁(FePc)粉体和石墨烯(G)共研磨热压法制备了G/FePc复合材料,研究了G对FePc耐热性能和吸波性能的影响。采用SEM和XPS表征了G/FePc复合材料的表面形貌和G与FePc之间的相互作用,结果发现,FePc均匀地吸附于G片层表面,且固化后形成了层状结构,从而改善了G/FePc复合材料的耐热性能和吸波性能。进一步通过TGA和矢量网络分析方法研究了不同G添加量对G/FePc复合材料的耐热性能和电磁性能的影响,并对G/FePc复合材料不同厚度的吸波性能进行了模拟分析。结果表明,G/FePc复合材料的耐热性能和吸波性能均随着G含量的增加而提高,当G添加量为5%(质量比)时,G/FePc复合材料在1 000℃热解残留率达到62.2%,在3.5mm厚度下最大反射损耗达到-30.50dB,反射损耗小于-10dB的带宽为1.38GHz,具有优良的耐热性能和吸波性能。
Graphene/iron phthalocyanine(G/FePc)composites were prepared by co-grinding and hot-press molding.The microstructure of G/FePc composites was examined by SEM and the interaction between G and FePc was examined by XPS.It’s found that FePc is uniformly absorbed on G and G/FePc composites form layer-like structure after solidification,which improves the heat resistance and wave absorbing properties.The effect of G content on the heat resistance and electromagnetic properties of G/FePc composites was further explored by TGA and vector network analysis,and the wave absorbing properties of G/FePc composites were simulated.The results show that the heat resistance and wave absorbing properties of G/FePc composites increase with G content increasing.When the G content is 5%(mass ratio),the char yield reaches 62.2% at 1 000℃,the maximum reflectivity reaches-30.5 dB with the thickness of 3.5 mm and bandwidth of reflectivity less than-10 dB is 1.38 GHz.
