As a type of two-dimensional (2D) material, MXene is known for its high electrical conductivity, excellent mechanical strength, and a variety of surface functional groups. These characteristics make it a promising candidate for flexible transparent conducting electrodes. In this study, MXene thin films were fabricated on polyethylene terephthalate (PET) substances using a dispersion of $Ti_3C_2T_x$-MXene. Transmittance measurements in the visible light range, electrical resistivity measurements, and bending durability tests were performed and compared with indium tin oxide (ITO), which has been widely used as a transparent conducting electrode. A transmittance of 87 %, a sheet resistance of 1320 Ω/sq, and flex durability were observed. Therefore, MXene thin films exhibited promising features as an alternative material to ITO for flexible transparent optoelectronics applications.
