Excellent microwave absorption properties based on a composite of one dimensional Mo 2 C@C nanorods and a PVDF matrix.

MoO 3 nanowires were synthesized by a wet chemical process and then coated by glucose, and finally successfully turned into Mo 2 C@C nanorods by carbonation reaction. An excellent absorption strength of -39.0 dB and absorption bandwidth of 12.2 GHz in the thickness range of 2.0-5.0 mm were achieved by the Mo 2 C@C/PVDF with 10% filler content, derived from effective Debye dipolar relaxation processes. It is expected that the composite can be applied as a novel and desirable microwave absorber.
