摘要
MXene, as a new 2-dimensional (2D) material, has excellently potential applications in the field of electrochemistry owing to its high conductivity and fast charge transporting speed. Especially, MXene/polymer composites have attracted widely attentions due to their extensive application in the area of multi-functional materials. Herein, the composites of Ti3C2Tx MXene/polyaniline (PANI) with different PANI contents have been successfully prepared. The microwave absorption mechanism of these materials was investigated. Attributing to the multiple layer structure, the dielectric property of Ti3C2Tx MXene and PANI, and the synergistic effect between the Ti3C2Tx and PANI, the as-prepared composites possessed a specific microwave absorbing behavior. With a proper content of PANI, the MXene/PANI composites in a paraffin matrix exhibited a maximum reflection loss of −56.30 dB at 13.80 GHz with the thickness of 1.8 mm. In addition, the effective absorption bandwidth (>90%) ranged from X-band (8–12.4 GHz) to Ku-band (12.4–18 GHz) with the tunable thickness ranging from 1.5 to 2.6 mm. The results indicate that MXene/PANI composites has great potential to be used in the field of microwave absorption.
