Kurzfassung:
With the growing popularity in digital systems and electronic communication equipment, there is an urgent need to develop lightweight, green, and efficient electromagnetic interference (EMI) shielding materials to handle the increasingly serious problem of radiation pollution. Herein, Ti 3 C 2 T x (MXene)/natural wood (NW) composites were prepared using a vacuum-pulse impregnation method and characterized by Fourier transform infrared (FTIR), scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD) patterns, X-ray photoelectron spectroscopy (XPS) analysis, and EMI shielding performance. As demonstrated, Ti 3 C 2 T x nanosheets were successfully inserted into wood matrices, and hydrogen bonding between Ti 3 C 2 T x nanosheets and cellulose nanofibers induced the fabrication of Ti 3 C 2 T x /NW composites. Ti 3 C 2 T x /NW composites exhibited excellent EMI shielding effectiveness (SE) values of 28.2 dB at the X-band frequency.
