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.

具有电磁屏蔽性能的MXene /木基复合材料

随着数字系统和电子通信设备的日益普及，迫切需要开发轻巧，绿色和高效的电磁干扰（EMI）屏蔽材料，以解决日益严重的辐射污染问题。本文采用真空脉冲浸渍法制备了Ti 3 C 2 T x（MXene）/天然木（NW）复合材料，并通过傅里叶变换红外光谱（FTIR），扫描电子显微镜（SEM），能量色散X射线光谱法对其进行了表征。 （EDX），X射线衍射（XRD）模式，X射线光电子能谱（XPS）分析和EMI屏蔽性能。如图所示，Ti 3 C 2 T x纳米片已成功插入木材基体中，Ti 3 C 2 T x纳米片与纤维素纳米纤维之间的氢键作用诱导了Ti 3 C 2 T x / NW复合材料的制备。Ti 3 C 2 T x / NW复合材料在X波段频率下具有28.2 dB的出色EMI屏蔽效果（SE）值。
