Hollow carbon microspheres modified with NiCo2S4 nanosheets as a high-performance microwave absorber

Ni Flower/MXene-Melamine Foam Derived 3D Magnetic/Conductive Networks for Ultra-Efficient Microwave Absorption and Infrared Stealth

“…In addition, abundant terminating functional groups and inherent defects of layered MXene will cause dipole polarization and defect polarization under highfrequency EM fields. Third, under the action of alternating EM fields, the Ni flower attenuated EM waves through natural resonance and exchange resonance [58][59][60][61][62][63][64][65][66][67]. Finally, the 3D porous network structure could increase the propagation path of microwaves in the foam, and the microwaves absorption efficiency could be improved after multiple reflection and scattering [68], while the microwaves also reflect and scatter between MXene and Ni flower.…”

High performance microwave absorption of light weight and porous non-carbon-based polymeric monoliths via a gel emulsion template

“…Moreover, M2-M5 still had excellent absorption performance; the RL min value of M2 could reach Furthermore, the microwave absorption abilities of the porous materials have been listed in Table 3. 38,39,[74][75][76][77] The above results show that the MA materials M1-M6 made by this novel strategy have effective microwave absorption performance. The absorption intensity, bandwidth and thickness can be effectively adjusted through the porosity of the monoliths.…”

Facile synthesis of ultralight S-doped Co3O4 microflowers@reduced graphene oxide aerogels with defect and interface engineering for broadband electromagnetic wave absorption

“…These results suggest that the magnetic loss in S-Co 3 O 4 @RGO is weaker than that of pure Co 3 O 4 . 66,67 According to the transmission line theory, the RL values are calculated by the measured electromagnetic parameters at a given layer thickness using the following equations [68][69][70] :…”
