Dielectric Loss Mechanism in Electromagnetic Wave Absorbing Materials

“…Functional groups are rich in most carbonaceous materials including carbon fibers, carbon nanotubes, biochar, and graphene. [ 97 , 98 , 99 , 100 ] Besides, the emerging MXene materials also possess abundant functional groups and can provide intense dipolar polarization. [ 101 , 102 ] The presence of these functional groups can be detected by deconvolution of high‐resolution XPS spectra of C and infrared spectroscopy.…”

Plasmonic hot-electron assisted phase transformation in 2D-MoS2 for the hydrogen evolution reaction: current status and future prospects

“…It is evident from recent research publications that the development of 2D atomically thin layered materials, such as graphene and TMDs, has stimulated a promising path for energy conversion and storage. 16,[166][167][168][169][170][171][172][173] Atomically thin 2D layered TMD materials have emerged with fascinating applications related to both scientic interpretations and technical perceptions. In particular, 2D-MoS 2 is probably one of the highest studied layered materials compared to other layered TMDs due to its feasible band gap, high electron mobility, rapid semiconducting to metallic phase transformations, and higher rate of charge transfer, high electrocatalytic activity, and stability.…”

Enhanced microwave absorption properties of reduced graphene oxide/TiO2 nanowire composites synthesized via simultaneous carbonation and hydrogenation

“…Recently, graphene as an MA material for high-performance microwave attenuation has grabbed considerable attention owing to its low density, high specific surface area, strong dielectric loss, and high electronic conductivity. [7][8][9] Nevertheless, graphene is still faced with several key issues such as impedance mismatching with air and narrow bandwidth for qualified absorption, which have hindered the practical applications of graphene-based nanocomposites in the field of microwave absorption. [10][11][12] In order to address the interfacial impedance mismatching of sole graphene materials, the incorporation of other lossy materials holds great promise as an imperative solution to improve their MA performance.…”
