▎ 摘 要
Graphene nanoplatelets (GNPs) and BaTiO3 particles filled epoxy coating with wide microwave absorption bandwidth were designed and investigated in the frequency range of 2-18 GHz. The microstructures of these coatings exhibit a uniform dispersion of GNs and BaTiO3 particles in the matrix. The double-layer structure and frequency selective surfaces (FSS) design were used to improve their microwave absorption of such coatings. A bandwidth of reflection loss (RL)
