“…In the S 2p spectra (Fig. 5e), three peaks show that the binding states of sulfur are 2p 3/2 splitting (S 2p 3/2 ) and 2p 1/2 splitting(S 2p 1/2 ) of the S 2p spin-orbital, and oxidized-S, which located at 164.2, 165.5 and 168.2 eV, respectively [43]. The doping of S usually replaces the carbon atoms located at the defect sites and edges, which promotes the increase of the graphite layer spacing, and oxidized-S https://engine.scichina.com/doi/10.1016/j.jechem.2020.06.025 has a strong binding force with sodium ions [44].…”

“…Benefitting from improved impedance matching and large specific surface area, the minimum RL value of CoS 2 /N-CNTs could achieve –65 dB and the EAB could reach 6.2 GHz with the thickness of 1.6 mm. Besides, Liu et al reported carbon cloths@N-doped carbon/CoS 2 by sulfuring carbon cloths@ZIF-67 [ 110 ]. The nanocomposite delivered a minimum RL value of –59.6 dB at 2.8 mm and a EAB of 9.2 GHz with the thickness of 2.5 mm.…”

To tackle the aggravating electromagnetic wave (EMW) pollution issues, high-efficiency EMW absorption materials are urgently explored. Metal–organic framework (MOF) derivatives have been intensively investigated for EMW absorption due to the distinctive components and structures, which is expected to satisfy diverse application requirements. The extensive developments on MOF derivatives demonstrate its significantly important role in this research area. Particularly, MOF derivatives deliver huge performance superiorities in light weight, broad bandwidth, and robust loss capacity, which are attributed to the outstanding impedance matching, multiple attenuation mechanisms, and destructive interference effect. Herein, we summarized the relevant theories and evaluation methods, and categorized the state-of-the-art research progresses on MOF derivatives in EMW absorption field. In spite of lots of challenges to face, MOF derivatives have illuminated infinite potentials for further development as EMW absorption materials.

“…Therefore, it is of great significance to develop absorbing materials with electromagnetic wave absorbing ability that can both mind the requirements of "wide, thin, light and strong" [1][2][3][4]. Moreover, the miniaturization and integration of electronic circuits and components put forward the request of flexible portable microwave absorption electronic devices [5,6]. Two-dimension (2D) materials, such as reduced graphene oxide (RGO) [7][8][9][10], MoS 2 [11][12][13][14][15], and new member Mxene [16][17][18][19], are usually applied as microwave absorber owing to their high specific surface area and abundant functional groups as well as defects, which will enhance the propagation paths of incident electromagnetic wave (EMW) inside absorbers by scattering effect and increase the loss through polarization relaxation loss.…”

Phase engineering is an important strategy to modulate the electronic structure of molybdenum disulfide (MoS2). MoS2-based composites are usually used for the electromagnetic wave (EMW) absorber, but the effect of different phases on the EMW absorbing performance, such as 1T and 2H phase, is still not studied. In this work, micro-1T/2H MoS2 is achieved via a facile one-step hydrothermal route, in which the 1T phase is induced by the intercalation of guest molecules and ions. The EMW absorption mechanism of single MoS2 is revealed by presenting a comparative study between 1T/2H MoS2 and 2H MoS2. As a result, 1T/2H MoS2 with the matrix loading of 15% exhibits excellent microwave absorption property than 2H MoS2. Furthermore, taking the advantage of 1T/2H MoS2, a flexible EMW absorbers that ultrathin 1T/2H MoS2 grown on the carbon fiber also performs outstanding performance only with the matrix loading of 5%. This work offers necessary reference to improve microwave absorption performance by phase engineering and design a new type of flexible electromagnetic wave absorption material to apply for the portable microwave absorption electronic devices.
