Excellent microwave absorption properties based on a composite of one dimensional Mo2C@C nanorods and a PVDF matrix

Abstract

MoO₃ nanowires were synthesized by a wet chemical process and then coated by glucose, and finally successfully turned into Mo₂C@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 Mo₂C@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.
