Excellent microwave absorption of carbon black/reduced graphene oxide composite with low loading

Absorbents with lightweight, low filler loading and broadband absorption are highly desired in electromagnetic wave absorbing field. Herein, the carbon black/reduced graphene oxide (CB/RGO) composite materials were fabricated via a facile synthetic method. The composite absorbents demonstrate an exc...

Zusammenfassung:	Absorbents with lightweight, low filler loading and broadband absorption are highly desired in electromagnetic wave absorbing field. Herein, the carbon black/reduced graphene oxide (CB/RGO) composite materials were fabricated via a facile synthetic method. The composite absorbents demonstrate an excellent microwave absorption performance. With the low filler loading of 7 wt%, the maximum absorption is as strong as 47.5 dB and the effective absorption bandwidth (reflection loss
