Estimating the term…
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.
A wave absorbing material comprising titanium sulfide (TiS) nanomaterial and paraffin, wherein the TiS nanomaterial is in a form of dispersed first micro-particles, wherein the dispersed first micro-particles are bulks of stacked first two-dimensional nano-sheets, wherein each of the first micro-particles has a size of 25-100 microns and the titanium sulfide nanomaterial has a molar ratio of Ti ions to S ions of 1:40 and wherein the titanium sulfide nanomaterial and paraffin form a wave-absorbing composite.
A wave absorbing material comprising MnO2—TiS composite nanomaterial and paraffin, wherein the MnO2—TiS composite nanomaterial is in the form of dispersed second micro-particles, wherein the dispersed second micro-particles are bulks of stacked second two-dimensional nano-sheets, wherein each of the second micro-particles has a size of 25-100 microns and the MnO2—TiS composite nanomaterial has a molar ratio of Ti ions to S ions of 1:40 and wherein the MnO2—TiS composite nanomaterial and paraffin form a wave-absorbing composite.
