Fig. 6: Schematic illustration of the MXenegel as a light-responsive conducting wire.

a The 30 wt% MXenegel is first injected into the transparent tube. After UV light irradiation, the MXenegel becomes sol-like and flows to the other side by tilting the tube. Then, the MXenegel is irradiated with visible light and transforms to gel-like again. b–e Digital images of the MXenegel wire and the light-responsive phase behavior demonstration. f The circuit diagram of MXenegel as an on-demand switch to lighten up LEDs. The MXenegel inside a transparent tube as a switch is also indicated. g, h After irradiated with UV and visible light, the MXenegel flows to the opposite end embedded with electrodes, by which the on-demand switch control of LEDs can be realized.
