Piezoresistive Sensors Based on Electrospun Mats Modified by 2D Ti₃C₂T_x MXene

The preparation methodology and properties of electroconductive, electrospun mats composed of copolyamide 6,10 and Ti₃C₂T_x are described in this paper. Mats of several compositions were prepared from a solution of n-propanol. The obtained electrospun mats were then tested as piezoresistive sensors. The relative resistance (A_R) of the sensor increased with an increase in the Ti₃C₂T_x content, and materials with relatively higher electrical conductivity displayed noticeably higher sensitivity to applied pressure. The pressure-induced changes in resistivity increased with an increment in the applied force.
