Description
Summary:Ti3C2Tx MXene has attracted extensive attention in the field of electromagnetic (EM) protection over recent years. Multilayer Ti3C2Tx (M-Ti3C2Tx), as an intermediate product of MXene ultra-thin structure, has potential advantages in the field of EM protection. Herein, the M-Ti3C2Tx was obtained by HCl/LiF etching Ti3AlC2. The microwave absorption (MA) and electromagnetic interference (EMI) shielding performance of Ti3AlC2 and M-Ti3C2Tx were compared. The mechanism research of MA and EMI shielding indicates that the construction of local conductive network plays a leading role in the EM wave attenuation. The sample with 30% M-Ti3C2Tx display RLmin of −50.26 dB, and corresponding bandwidth of 4.64 GHz at the thickness of 1.7 mm. Especially, the metastructure based on the EM parameters of M-Ti3C2Tx/wax exhibits ultra-wide bandwidth (15.54 GHz). Our research will provide a basis for the design of MXene-based EM protection performance.
