摘要:
采用溶剂热法制备出BaTiO3纳米颗粒,将不同质量的BaTiO3纳米颗粒与氧化石墨烯(GO)进行复合,并在氩气保护下经过煅烧得到BaTiO3/还原氧化石墨烯(BaTiO3/RGO)纳米复合物.利用X射线衍射(XRD)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)等手段系统地表征了样品的物相结构以及表面形貌,并用矢量网络分析仪(VNA)测试样品的微波吸收特性.当制备的BaTiO3/RGO纳米复合物中BaTiO3的质量分数为80.9%时,纳米复合物展现了良好的微波吸收性能; 当其厚度为2.0 mm时,在频率为10.48 GHz处的反射损耗达到-26.06 dB,且在9.32~11.54 GHz频段内反射损耗小于-10 dB.实验结果表明,BaTiO3/RGO纳米复合物具有优异的电磁波吸收性能.
Abstract:
Barium titanate(BaTiO3)nanoparticles were synthesized by solvothermal method and then the barium titanate/reduced graphene oxides(BaTiO3/RGO)nanocomposites with different mass ratios were obtained after calcining in argon.The structures and morphologies of samples were systematically characterized using X-ray powder diffraction(XRD),scan electron microscope(SEM)and transmission electron microscope(TEM).The microwave absorption properties of samples were tested using vector network analyzer(VNA).When the mass fraction of BaTiO3 was 80.9%,the as-prepared BaTiO3/RGO nanocomposite showed excellent microwave absorption properties,its minimum reflection loss value was -26.06 dB at 10.48 GHz with the thickness of 2.0 mm,and the bandwidth of reflection loss value less than -10 dB was from 9.32 GHz to 11.54 GHz.The results showed that BaTiO3/RGO nanocomposite had outstanding microwave absorption properties.
