Abstract

A novel one-dimensional carbon-supported Ni/Mo₂C (Ni/Mo₂C-C) nanocomposite with excellent electromagnetic wave absorption properties was successfully synthesized by annealing NiMoO₄@PDA directly, and then the (Ni/Mo₂C-C)/polyvinylidene fluoride (PVDF) composites were fabricated using a simple blending and hot-molding technique. An excellent reflection loss (RL) of -55.91 dB at 9.28 GHz with a low filler loading (15 wt%) and effective bandwidth (RL < -10 dB) of 14.12 GHz in the thickness range of 1.5-5.0 mm was obtained. Dielectric loss is considered to be the dominant mechanism of (Ni/Mo₂C-C)/PVDF, which was confirmed by the Debye relaxation process and attenuation theory.
