Enhanced wave-absorption properties of nanocomposites based on the synthesized Bi₂S₃ nanorods and polyvinylidene fluoride

In this study, Bi₂S₃ nanorods were synthesized on a large scale through a simple hydrothermal method at low temperature. To investigate the wave-absorption properties of Bi₂S₃ nanorods, the homogeneous nanocomposites consisting of the nanorods and paraffin or polyvinylidene fluoride (PVDF) matrix were fabricated and characterized. The results indicated that the introduction of Bi₂S₃ nanorods to PVDF significantly enhanced the wave-absorption properties of the absorber. The loss mechanism of Bi₂S₃/PVDF nanocomposites with different loadings was discussed and some theories were also employed to explain the mechanism of the enhancement based on the experimental results.
