摘要
以Hummers法制备得到的氧化石墨烯和四氧化三铁为前驱体,分别通过水热法和共沉淀法成功制备了还原石墨烯与Fe_3O_4复合粉体.使用红外吸收光谱(FT-IR),X-射线衍射光谱(XRD)和动态光散射仪(DLS)对G-Fe_3O_4复合粉体晶体结构和粒径进行表征,并对G-Fe_3O_4复合粉体吸波加热性能进行了初步研究,结果表明两种工艺成功制备了GFe_3O_4复合材料;水热法制备的G-Fe_3O_4复合材料比共沉淀法简单且得到的粉体性能更优.研究发现粉体的吸波加热性能与其制备的方法有关;与粉体用量有关;在达到一定升温效果后其升温与其加热时间基本无关.
Graphene oxide made by the Hummers method and ferroferric oxide was used as precursors to reduce the graphene and Fe3O4 composite powder materials (G-Fe3O4)with the hydrothermal method and copreeipitation method respectively.The structure and particle size of G-Fe3O4 composites were characterized by FT-IR,X-ray diffraction(XRD)and dynamic light seattering(DLS).The results showed that the preparation of G-Fe3O4 composite was successful.A preliminary study on the absorb- ing wave performance of G-Fe3O4 composite was carried out,and the G-Fe3O4 composite was a powder material with good microwave absorption properties.
