State-of-the-art progresses for TiCT MXene reinforced polymer composites in corrosion and tribology aspects.

TiCT MXene, a revolutionary 2D material, has shown bright prospects in various fields, including energy conversion and storage, electronic devices, electromagnetic interference shielding, catalysis, biomedicine etc. The large specific surface area, high electrical conductivity, abundant surface terminations, and the highest stiffness among all solution-processed 2D materials of TiCT MXene make it a rising star in polymer composites. Not only have TiCT MXene-based polymer composites come into prominence in sensing, energy storage, and photothermal conversion fields as is widely known, but they have also shown great potential in corrosion and tribology fields. Hence, this critical review provides a comprehensive overview of the synthesis strategies, mechanical, and tribological properties of TiCT MXene and the recent advances of TiCT MXene reinforced polymer composites in corrosion and tribology aspects. The challenges of TiCT-based polymer composites faced in corrosion and tribology fields are also summarized. This analysis of TiCT-based polymer composites will stimulate a booming field including but not limited to corrosion and tribology, bringing TiCT MXene from lab to engineering application.
