(a) T^–0.5 – 1 as a function of thickness (t, >20 nm), to obtain the optical conductivity (σ_op) of Ti₃C₂T_x thin films. (b) R_s as a function of t to extrapolate the average conductivity (σ_DC) of Ti₃C₂T_x thin films. (c) Comparison of average electronic conductivity in various transparent conductive films. Detailed values are presented in Table S4. (d) Changes in resistance of TCEs after folding at 180° for 10 000 cycles. (e) R_s as a function of time under ambient conditions. The large-sized and small-sized flakes form a film with T = 74% and T = 72%, respectively.
