Ni-modified Ti₃C₂MXene with enhanced microwave absorbing ability

Abstract

Ni-modification of Ti3C2MXene enables enhanced microwave absorption ability.

Sandwich-Like Fe&TiO2@C Nanocomposites Derived from MXene/Fe-MOFs Hybrids for Electromagnetic Absorption

“…Ti 3 C 2 T x is a representative of MXene family decorated with abundant active surface functional terminations [27][28][29], which could provide remarkable amount of dipolar and interfacial polarizations. Moreover, the variety surface terminations of MXene by ion intercalation [30], annealing [31], and oxidization [32] could offer tunable EMW absorbing properties. In general, EMW absorbers should have strong EM energy attenuation ability and moderate conductivity for impedance matching.…”

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

“…In 2016, two researcher groups, han, coworkers, and shahzad et al, reported the EMI shielding study on the MXene that established the 2D Mxene as the versatile material for EMI shielding application162,163 . Feng et al studied the Ni-modified Ti 3 C 2 MXene in the frequency range of 2-18 GHz164 . The effective absorbing bandwidth is greatly broadened, especially at the lower frequency of 2-8 GHz.…”

Enhancement of microwave absorption bandwidth of MXene nanocomposites through macroscopic design

“…The magnetic properties of Fe 3 O 4 @TiO 2 -Ti 3 C 2 T x MXene nanocomposite were explained elsewhere [17,18]. The RL (dB) of a perfect electric conductor (PEC)-backed material (figure 2a) can be expressed as [12][13][14][15][16][17][18][19] reflection loss (RL) ¼ 20log…”

“…MXene has been particularly noted by the scientific community in the last 8 years for its unique structure and electrical properties [12][13][14]. MXene's utilization for microwave absorption is increasing day by day; however, the understanding of its contribution is only related to its metal-like properties and surface-rich functional groups [1,[11][12][13][14][15][16][17][18]. In addition, the graphene-like two-dimensional materials with a multi-layer feature, MXene has a high dielectric loss in a polymer matrix at low percolation limit (15 wt%) [12].…”
