Ultra-High Electromagnetic Absorption Property of One-Dimensional Carbon-Supported Ni/Mo(2)C and Polyvinylidene Fluoride

A novel one-dimensional carbon-supported Ni/Mo(2)C (Ni/Mo(2)C-C) nanocomposite with excellent electromagnetic wave absorption properties was successfully synthesized by annealing NiMoO(4)@PDA directly, and then the (Ni/Mo(2)C-C)/polyvinylidene fluoride (PVDF) composites were fabricated using a simpl...

Descripción
Sumario:A novel one-dimensional carbon-supported Ni/Mo(2)C (Ni/Mo(2)C-C) nanocomposite with excellent electromagnetic wave absorption properties was successfully synthesized by annealing NiMoO(4)@PDA directly, and then the (Ni/Mo(2)C-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/Mo(2)C-C)/PVDF, which was confirmed by the Debye relaxation process and attenuation theory.
