Synthesis of porous carbon matrix with inlaid Fe3C/Fe3O4 micro-particles as an effective electromagnetic wave absorber from natural wood shavings

With the rapid growth in the use of wireless electronic devices, society urgently needs electromagnetic wave (EMW) absorbers with light weight, thin thickness, wide effective absorbing bandwidth and strong absorbing capacity. One kind of the most attractive absorbers is magnetic carbon composites. Here, we successfully synthesized porous carbon matrix with inlaid Fe3C/Fe3O4 micro-particles (CFF) by in-situ carbonization of pre-prepared...
