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.
