Preparation and microwave absorption performance of a flexible FeO/nanocarbon hybrid buckypaper and its application in composite materials.

Graphene oxide (GO) and carbon nanotubes are promising microwave-absorbing materials. Herein, ferroferric oxide (FeO)/multiwall carbon nanotube (MWCNT) and FeO/GO hybrid buckypapers with excellent flexibility and manoeuvrability were coated on the surface of an epoxy substrate to fabricate microwave-absorbing composites. FeO/GO buckypapers show a unique layered structure that differs from the complex network structure of FeO/MWCNT buckypapers.
