Electromagnetic interference shielding effectiveness in 3D flower-like MoS2-rGO/gadolinium-doped nanocomposites

Hydrothermal Synthesis of MoS2/rGO Heterostructures for Photocatalytic Degradation of Rhodamine B under Visible Light

“…As can be illustrated in Figure 5(a), the XRD patterns of the MoS 2 /rGO composites exhibit characteristic peaks at 2θ = 14:1; 33.6; 39.84; and 58.1°corresponding to the (002), (100), (103), and (110) planes, respectively, which are well agreed with the 2H hexagonal phase of MoS 2 [26]. The increase of MoS 2 /rGO mass ratio led to the gradually increase in intensity of MoS 2 -related peaks, which could be clearly observed at the (002) lattice plane.…”

“…The residual concentration of RhB was recorded using a UV-Vis spectrometer. [26]. These featured peaks in composites were obtuse and lower (peak at 002) than those of pristine MoS 2 due to the overlap of the rGO layers between MoS 2 crystals because of composite formation (as shown in Figure 1(a)).…”

The tunable electric and magnetic properties of 2D MXenes and their potential applications

“…The MoS 2 material is semiconductors (bandgap of ∼1.2 eV) with parabolic energy dispersion relation. The bandgap can be tuned by quantum confinement effect lead by different surface morphology; hence MoS 2 shows the candidacy for EMI shielding application 55,56 . As compared to 2D graphene, pure MoS 2 has lower electron conductivity and lower permittivity due to poor charge transfer.…”

Electromagnetic interference shielding with absorption-dominant performance of Ti3C2TX MXene/non-woven laminated fabrics

“…The total SE was calculated according equations (1) to (3). 29,30 According to equation (4), SSE t (ratio of specific shielding effectiveness (SSE) to thickness) was used to compare the SE of materials with different thickness and density. where SE T is total shielding effectiveness [dB], SE A is absorption effectiveness [dB], SE R is reflection effectiveness [dB], and t is the thickness of samples [cm].…”
