Summary: Nanocellulose-mediated MXene composites have been widely studied for their potential applications in sustainable energy, wearable sensors, and electromagnetic interference shielding. This study explored the effects of different nanocelluloses, including bacterial cellulose, cellulose nanocrystals, and TEMPO-oxidized cellulose nanofibers, on the properties of nanocellulose/Ti3C2TX composites. The results showed that the self-assembly process improved the dispersibility, film-forming ability, mechanical properties, and multifunctional performances of the composites. The optimized TOCN/Ti3C2TX film exhibited excellent tensile strength, long-term stability, favorable photoelectric response, and temperature response. Laser-cutting patterned TOCN/Ti3C2TX films were used to assemble flexible multifunctional electronics with splendid photoresponse performances and tunable electromagnetic energy shielding capability. This research provides a novel pathway for the design of wearable EMI devices with photoelectric response and photothermal conversion.
