Enhanced Wave-Absorption Properties of Nanocomposites Based on the Synthesized Bi2S3Nanorods and Polyvinylidene Fluoride

Abstract In this study, Bi 2 S 3 nanorods were synthesized on a large scale through a simple hydrothermal method at low temperature. To investigate the wave‐absorption properties of Bi 2 S 3 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 Bi 2 S 3 nanorods to PVDF significantly enhanced the wave‐absorption properties of the absorber. The loss mechanism of Bi 2 S 3 /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.
