纳米铁氧体/石墨烯复合材料的制备研究进展

Progress in preparation of nano ferrite/graphene composites

石墨烯/铁氧体复合材料由于复合单体石墨烯与铁氧体两者特殊的结构和性质引起了国内外研究者的极大兴趣。石墨烯结构特殊,性能优异却由于其本身存在的层间易团聚现象导致了有效比表面积减小,比电容等性能下降,铁氧体具有高的比容量却电导率低,为了有效地克服二者的不足并充分利用其优势,近年来研究者们不断研究两者的复合制备方法。介绍了复合材料的制备方法的最新研究进展,并对其应用前景进行了展望。

Graphene/ferrite composites is very attractive for many domestic and foreign researchers in this field.The effective surface area and the capacitance properties of graphene decrease a lot because of the existence of inter agglomerate phenomenon although it has special structure and excellent performance.Besides,ferrite has high specific capacity but low conductivity.Thus,in recently years,researchers have tried to studied the composite preparation method in order to effectively overcome the shortcomings of the two materials and make full use of their advantages.The latest research progress of composite preparation methods of the composite materials is introduced and the prospect is also discussed.
