Abstract: As a novel two-dimensional layered nano material, MXene has large specific surface area and rich surface functional groups. When used as a filler in polymer composites, it can significantly improve the performance or broaden the application of polymer. Therefore, it has been widely studied at present. In this paper, the preparation methods of MXene and MXene/polymer composites are briefly summarized. The mechanical, thermal, tribological and electromagnetic shielding properties of MXene/polymer composites are described, and the latest research progress has been summarized. Finally, the prospects are made on the main problems and for its future development orientation.
