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.
