RGO/BaTiO_3复合材料的制备与性能研究
|
摘要
采用改进的Hummer法制备氧化石墨烯(GO),以乙二醇为还原剂将GO还原得到RGO(Reduced graphene oxide),并通过物理共混法制备RGO/BaTiO3复合材料。采用扫描电镜、X射线衍射、傅里叶红外、介电性能测试仪等对其表面形貌、微观结构、介电性能进行了表征。结果表明,乙二醇为还原剂成功实现了GO的还原,且还原后的RGO有效提高了RGO/BaTiO3复合材料的介电性能。当RGO质量分数为0. 5%～0. 8%时,复合材料的介电常数高达140以上,比纯BaTiO3材料提高约1. 75倍,且介电损耗控制在0. 2～0. 45之间。
The modified Hummer method is used to prepare graphene oxide(GO),and GO is reduced by ethylene glycol into RGO(reduced graphene oxide),then RGO/BaTiO_3 composite materials are prepared by blending RGO with BaTiO_3. The surface morphology,microstructure,dielectric properties of samples are characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD),Fourier infrared(FT-IR) and dielectric performance tester. The results show that GO is reduced successfully with ethylene glycol as a reducing agent. RGO improves effectively the dielectric performance of RGO/BaTiO_3 composite materials.The dielectric constant of the composite materials that contains 0. 5%-0. 8% of RGO exceeds 140,approximately 1. 75 times higher than pure BaTiO_3,and the dielectric loss is controlled between 0. 2-0. 45.
