Optimizing impedance matching by a dual-carbon Co-regulation strategy of Co3O4@rGO/celery stalks derived carbon composites for excellent microwave absorption

Xiubo Xie et al.

Summary: Both macroscopic composition and microstructure should be considered for reasonable microwave absorbent designing. In this study, Co3O4@reduced graphene oxide (rGO)/Celery stalks derived carbon (CDC) composite was prepared, and the dielectric and impedance matching properties of the composites were successfully regulated by changing the mass ratio of rGO to CDC. The Co3O4@rGO/CDC composite with multiple components and 3D net structure showed promising magnetic/dielectric loss combinations, interfacial polarization, and multiple reflections and scattering, while the unique structure of CDC contributed to the optimization of impedance matching. The strategy of co-regulating dielectric properties of materials with double carbon provides a novel pathway for the preparation of lightweight, low-cost, and high-performance absorbers.
