摘要：
A novel metal organic framework (MOF) coated RGO was fabricated by a one-step method. The morphology and microstructure of MOF-53(Fe)/RGO composite were characterized by XRD and TEM. The electromagnetic parameters indicate that MOF-53(Fe)/RGO composite shows enhanced electromagnetic absorption properties compared with MOF-53(Fe). The maximum R-L can reach -25.8 dB at 15.4 GHz and the absorption bandwidth with the reflection loss exceeding -10 dB is 5.9 GHz (from 12.1 to 18 GHz) with the thickness of 2 mm. The possible absorption mechanism was also investigated in detail. Our results indicate the potential application of MOF/RGO composite as a more efficient microwave absorber. (C) 2016 Elsevier B.V.
