摘      要：In recent years,electromagnetic wave(EMW)absorption has been extensively investigated for solving EMW radiation and *** metal-organic frameworks(MOFs)have attracted attention due to their low density and unique structure,which can meet the requirements of strong reflection loss(RL)and wide absorption bandwidth of EMW absorption *** this manuscript,indium nanoparticles/porous carbon(In/C)nanorods composites were prepared via the pyrolysis of nanorods-like In-MOFs at a low temperature of450°*** nanoparticles are evenly attached and embedded on porous *** electrical conductivity of In/C nanorods is unfavorable to EMW absorption performance,which is due to the low temperature ***,graphene(Gr)nanosheets with high electrical conductivity are introduced to adjust electromagnetic parameters of In/C nanorods for enhancing EMW *** minimum RL of the In/C-Gr-4 composite is up to-43.7 dB with a thin thickness of 1.30 *** addition,when the thickness is further reduced to 1.14 mm,the minimum RL of-39.3 dB at 16.1 GHz and effective absorption bandwidth of 3.7 GHz(from 14.3 to 18.0 GHz)can be *** work indicates that In/C-Gr composites show excellent EMW absorption performance.
