摘要:A three-dimensional (3D) structure carbon foam for microwave absorption is synthesized by a facile template method using coal liquefaction residue (CLR) as carbon source. The results have shown that the sample made under optimized conditions has exhibited a broad effective absorption bandwidth up to 5.8 GHz in a range of 2-18 GHz with a reflection loss <= -10 dB. The magnetic Fe species derived from CLR are homogeneously dispersed in the 3D scaffold of carbon foam, which increase the magnetic loss, interface polarization relaxation and the synergetic effect between the magnetic Fe species and the dielectric carbon foam matrix.
