a Digital images of the MXenegel as conductive inks and the written NYCU. b A wire printed by 30 wt% MXenegel can directly lighten up an LED bulb without any amplifier. c A long-duration experiment of mechanical cleavage test shows the repeated open and close circuit stability and current change performance of the 30 wt% MXenegel wire. d The conductivities of MXenegels with different MXene doping ratios. The error bars are the standard deviations calculated from 10 data points. e Nyquist plot of 30 wt% MXenegel after UV and visible light irradiations. f Impedance changes of 5 wt% MXenegel over the temperature range of 10–60 °C.
