Controllable construction design of Co@C@MWCNTs interpenetrating composite with tunable enhanced electromagnetic wave absorption

Lightweight absorbers with strong broadband microwave absorption are highly desired in military and civil fields. In this work, a 3D interpenetrating network formed from a Co@C@ MWCNTs composite was synthesized via a combined wet chemical and pyrolysis route. Because of strengthening interfacial pol...

Zusammenfassung:Lightweight absorbers with strong broadband microwave absorption are highly desired in military and civil fields. In this work, a 3D interpenetrating network formed from a Co@C@ MWCNTs composite was synthesized via a combined wet chemical and pyrolysis route. Because of strengthening interfacial polarization, suitable impedance matching and synergistic effects, the Co@C@MWCNTs hierarchical composite exhibited outstanding microwave absorption properties. An optimal reflection loss reached − 55.7 dB at 8.7 GHz and its effective bandwidth ( R L
