Broadband high-performance microwave absorption of the single-layer Ti3C2Tx MXene
文献摘要：
MXenes,a family of two-dimensional(2D)materials,exhibit peculiar microwave-absorbing behaviors due to their unique chemical composition and structure.Although laminated Ti3C2Tx MXenes with a multi-layer structure have been used for microwave absorption,real 2D MXenes with a single-layer structure have not yet been investigated.Here,the electromagnetic wave response behavior of single-layer Ti3C2Tx MXenes was explored in detail.The permittivity of Ti3C2Tx MXene rises dramatically with an increase in filler loading,and Ti3C2Tx MXene features a distinct dielectric response wherein dipolar polarization and interfacial polarization makes a greater contribution at low filler loading;conductive loss becomes more prominent at high filler loading.Versus laminated Ti3C2Tx MXene,single-layer Ti3C2Tx MXene delivers superior absorbing capability:The RLmin value of SL-Ti3C2Tx-22％reaches-43.5 dB at 6.5 GHz,and a broad EAB of 6.88 GHz can be attained at a thickness of 1.8 mm due to enhanced dipolar polarization,interfacial polarization,and conductive loss.This work is of great significance in guiding the future development of MXene-based absorbers.
