摘要：

Quasi-one-dimensional (Q1D) nickel nanostructures were prepared by a facial wet chemical process, and then the nickel chains/polyvinylidene fluoride (PVDF) composites were fabricated using the hot-molding procedure. Both the complex permittivity and permeability of the Ni/PVDF composites could be artificially adjusted by changing the nickel proportions, which contribute to enhancing the microwave absorption. An excellent reflection loss (RL) of -42.08 dB at 7.4 GHz with a low filler loading(20 wt%) and effective bandwidth (RL <-10 dB) of 10.7 GHz in the thickness range of 2-5 mm was obtained, which is expected that Ni/PVDF nanocomposites can be used as a novel and highly efficient microwave absorbers.
