主　　题：electromagnetic wave absorption three dimensional network structure melamine sponge derived carbon non-stoichiometric carbide 

摘      要：Non-stoichiometric carbides have been proven to be effective electromagnetic wave(EMW)absorbing *** this study,phase and morphology of XZnC(X=Fe/Co/Cu)loaded on a three dimensional(3D)network structure melamine sponge(MS)carbon composites were investigated through vacuum filtration followed by *** FeZnC/CoZnC/CuZnC with carbon nanotubes(CNTs)were uniformly dispersed on the surface of melamine sponge carbon skeleton and Co-containing sample exhibits the highest CNTs *** minimum reflection loss(RL_(min))of the CoZnC/MS composite(m_(composite):m_(paraffin)=1:1,m represents mass)reached-33.60 dB,and the effective absorption bandwidth(EAB)reached 9.60 *** outstanding electromagnetic wave absorption(EMWA)properties of the CoZnC/MS composite can be attributed to its unique hollow structure,which leads to multiple reflections and *** formed conductive network improves dielectric and conductive *** incorporation of Co enhances the magnetic loss capability and optimizes interfacial polarization and dipole *** simultaneously improving dielectric and magnetic losses,ex-cellent impedance matching performance is *** clarification of element replacement in XZnC/MS composites provides an effi-cient design perspective for high-performance non-stoichiometric carbide EMW absorbers.
