Preparation and Microwave Absorption Properties of Barium Titanate/Reduced Graphene Oxides Nanocomposite
摘要
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 mi-crowave 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.关键词
