Abstract: Ti₃C₂T_x MXene is a new type of graphene layered two-dimensional material with high hydrophilicity, electrical conductivity, stability and mechanical properties, which has attracted much attention in the field of flexible sensors. However, due to the self-accumulation problem of Ti₃C₂T_x MXene, the surface active sites are reduced and the rapid transfer of particles is limited. Therefore, the performance of Ti₃C₂T_x MXene needs to be modified and optimized. Recent research progress of two-dimensional Ti₃C₂T_x composites for flexible sensors is reviewed. By combining with carbon materials, transition metal oxides, conductive polymers and other materials, both the mechanical and electrochemical properties of Ti₃C₂T_x can be significantly improved for the applications as flexible sensors.
