摘　　要：采用微波还原技术制备还原氧化石墨烯(rGO),将rGO和Fe_3O_4粒子通过化学共沉淀法覆盖在预先镀银的空心玻璃微珠(HGM)表面,考察该复合粒子的结构组成和吸波性能。X射线衍射分析(XRD)和透反射偏光显微镜观察表明,rGO及Fe_3O_4粒子成功地均匀包覆在HGM表面;玻璃微珠的中空结构能够明显减小复合粒子的密度。当r GO质量分数为20%时,该复合粒子具有较好的吸波效果。The reduced graphene oxide （rGO） was fabricated by microwave technique. The rGO and Fe3 04 particleswere uniformly coated on the surface of the previous silver- coated hollow glass microspheres （HGM） by chemicalcoprecipitation method. The microwave absorbing properties of these, composite particles were studied. The results oftransparent polarizing microscope and the XRD observations showed that rGO and Fe3 04 particles were successfully coatedon the surfaces of the HGMs. The density of composite particles was obviously reduced due to the hollow structure ofHGMs. When the content of rGO was 20%, the good wave absorption effect of the composite particles was obtained.
