Abstract
A titanium sulfide (TiS) nanomaterial and a composite material thereof for wave absorption are disclosed. The TiS nanomaterial is in a form of dispersed micro-particles which are bulks formed by stacking two-dimensional nano-sheets. The TiS nanomaterial is a bulk formed by stacking two-dimensional nano-sheets, thereby having a laminated structure that improves the wave absorption effect. In addition, experimental results demonstrate that the TiS nanomaterial with a dose of 40 wt % has the most excellent wave absorption performance, with a minimum reflection loss up to −47.4 dB, an effective absorption bandwidth of 5.9 GHz and an absorption peak frequency of 6.8 GHz, which are superior to those of existing two-dimensional bulk materials. One of reasons for the excellent wave absorption performance of the TiS nanomaterial may be because the laminated micro-morphology of TiS results in the electromagnetic wave refraction loss.
