Electromagnetic characteristic and microwave absorbing performance of different carbon-based hydrogenated acrylonitrile-butadiene rubber composites

► Rubber microwave absorbing materials were prepared using three carbon fillers. ► Dielectric permittivity can be described using the effective medium theory. ► Microwave conductivity was described by parallel resistance-capacitance model. ► MWCNT composites have the best microwave absorbing performance of three kinds.
