Ti₃C₂MXene: a promising microwave absorbing material

Abstract

A novel microwave absorbing material with Ti3C2MXene nanosheets.

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

“…Due to the unique layered structure of these laminated materials, which possess large surface area and heterogeneous interfaces, abundant dipolar, and interfacial polarizations could be generated during EMW absorption process. This is believed to be the main contribution to the excellent EMW absorbing ability [7][8][9]. Specifically, the most widely studied laminated EMW absorbers was the graphene-based two-dimensional materials in the past decade [2,[9][10][11].…”

“…MXene is a new family member of the big family tree of two-dimensional (2D) materials [15,16], whose formula is M n+1 X n T x , where M is an early transition metal, X is carbon and/or nitrogen, and T x is the surface terminations usually −OH, -F, and/or -O [17][18][19]. Due to the laminated structure and unique combination of electrical conductivity and hydrophilicity, MXene is considered as an attractive candidate for various applications, including energy storage [16,20,21], sensors [22,23], electromagnetic absorption, and electromagnetic interference shielding [3,8,24,25]. Feng et al [8] synthesized Ti 3 C 2 T x nanosheets by HF system etching process, which appeared enhanced microwave absorption ability (RL value of − 40 dB at 2 mm thickness).…”

Fabrication of Nonwetting Flexible Free‐Standing MXene‐Carbon Fabric for Electromagnetic Shielding in S‐Band Region

“…reported that 80% of MXene–cellulose nanofiber composite displayed 25.8 dB of SE in the X‐band region with a thickness of 45 nm, while 90 wt % of MXene–cellulose nanofiber showed SSE/t of 2647 dB cm 2 /g. Feng et al . study showed that Ti 3 C 2 T x ‐paraffin composite with a thickness of 2 mm exhibited 40 dB of reflection loss in the C‐band region.…”

Carbon Nanofibers Propped Hierarchical Porous SiOC Ceramics Toward Efficient Microwave Absorption

“…The electromagnetic parameters of samples mixed with wax (50 wt.%) were measured at 2~18 GHz using Vector network analyzer (N5245A, Agilent). The reflection loss (RL) values were calculated based on transmission line theory using the following equations [16,17].…”
