摘要

The electromagnetic (EM) properties of both nitrogen-doped graphene (N-GP) and Ti3C2 nanosheets as hybrid absorbers were investigated in the frequency range of 2–18 GHz. The values and frequency dependencies of EM properties of such hybrid absorbers can be adjusted by the combination of the unique microstructure and dielectric characteristics of the N-GP and Ti3C2 nanosheets. The minimum reflection loss (RL) reaches up to ?52 dB and the bandwidth below ?10 dB can be obtained in the frequency range of 10.9–18 GHz with a sample thickness of 1.4 mm. These results suggest that N-GP and Ti3C2 nanosheets as hybrid absorbers are highly promising fillers for dielectric and EM applications, especially for thin-thickness, broadband absorption microwave absorbers.
