摘要
以Co(NO_(3))_(2)·6H_(2)O和Fe(NO_(3))_(3)·9H_(2)O为原料,采用水热法制备石墨烯/CoFe_(2)O_(4)复合材料,利用SEM,XRD和矢量网络分析仪对样品的结构、形貌及吸波性能进行了分析与测试。结果表明当铁酸钴与石墨烯复合材料比例为10:4,频率在7.0GHz附近,最大反射损耗可达到-12.24dB。氧化石墨烯的加入有效地防止了粉末颗粒聚集成团的现象,氧化石墨烯和铁氧酸钴材料复合良好,加入氧化石墨烯并没有改变铁酸钴的结构,同时与单相铁酸钴相比,由于加入了氧化石墨烯,吸波性能得到了提升。
Based on Co(NO_(3))_(2)·6H_(2)O and Fe(NO_(3))_(3)·9H_(2)O as raw materials,graphene/CoFe_(2)O_(4)composite materials were prepared by water and heat and the structure,morphology and absorption performance of samples were analyzed and tested using SEM,XRD and vector network analyz-ers.When the ratio of cobalt iron acid to graphene composites is 10:4,the frequency is near 7.0 gigahertz,the maximum reflection loss is-12.24 deci-bels.The morphology of composite materials and the formation and wave absorption properties of graphene/CoFe_(2)O_(4)composites were also investigat-ed.The results show that graphene oxide effectively prevents the phenomenon of powder particles gathering into clumps,graphene oxide and cobalt ferric acid material swell,adding graphene oxide did not change the structure of cobalt ferrite,making the composite material look good.At the same time,compared with pure cobalt ferrite,due to the addition of graphene oxide,the absorption performance has also improved a lot.
