Herein, a flexible, durable, and high-performance cotton-based electrode was fabricated by in-situ polymerizedpolyaniline(PANI) andMXene(Ti3C2Tx) coating. MXene, as aconductive material, improved the conductivity of the PANI/Cotton composites significantly, which could promote electrochemical performance. The fabricated MXene/PANI@Cotton electrode displays a high capacitance of 1027.5 mF cm−2at the current density of 1 mA cm−2and stable capacitance retention. At the same time, the flexiblesupercapacitorbased on the MXene/PANI@Cotton electrodes shows high electrochemical performance and excellent stability under bending.
