Abstract

The electromagnetic properties of Ti3C2 nanosheets, prepared by immersing Ti3AlC2 powders in HF and subsequent ultrasonication, were first investigated in the frequency range of 12.4–18 GHz. The Ti3C2 nanosheet filled composites showed high relative complex permittivity and microwave absorption as compared to those filled with the original Ti3AlC2 powders under the same content. Reflection loss values of the Ti3C2 nanosheets filled composites exceeded −11 dB (more than 92% absorption) in the frequency range of 12.4–18 GHz with a thickness of 1.4 mm. These results suggest that the Ti3C2 nanosheets with unique dielectric properties are highly promising fillers for dielectric and electromagnetic applications.
