改性氧化石墨烯/Fe3O4复合材料的制备及电磁吸收性能
|
Abstract:
为改善氧化石墨烯（GO）/Fe3O4复合材料的分散程度，利用三苯基膦（PPh3）对GO表面进行功能化改性得到改性氧化石墨烯（GOP），然后采用共沉淀法一步合成GOP/Fe3O4复合材料。通过场发射SEM、高分辨TEM、XRD、FTIR、Raman和VSM对GOP/Fe3O4复合材料的形貌、结构和磁性能进行表征。利用矢量网络分析仪（PNA）测试了GOP/Fe3O4复合材料的电磁参数并模拟计算其对电磁波的吸收性能。结果显示：GOP/Fe3O4复合材料的最大电磁波吸收强度值达到-25.4 dB，有效吸收频宽为6.0 GHz，较未改性GO/Fe3O4复合材料均有大幅度提高。 In order to improve the dispersion degree of graphene oxide (GO)/Fe3O4 composites, modified graphene oxide (GOP) was obtained by functional modification of GO surface with triphenylphosphine (PPh3). GOP/Fe3O4 composites was synthesized in one step by coprecipitation method. The morphologies, structures and magnetic properties of GOP/Fe3O4 composites were characterized by SEM, TEM, XRD, FTIR, Raman and VSM. The electromagnetic parameters of the GOP/Fe3O4 composites were measured by phasor network analyzer (PNA), and the electromagnetic wave absorption properties of GOP/Fe3O4 composites were simulated. The results show that the maximum absorption peak value of GOP/Fe3O4 composites is -25.4 dB and the maximum absorption bandwidth is 6.0 GHz, which is greatly improved compared with the unmodified GO/Fe3O4 composites. 国家自然科学基金（51272010；51472018
