Abstract: Abstract MXene, a promising photothermal nanomaterial, faces challenges due to densely stacked nanosheets with high refractive index (RI). To maximize photothermal performance, MXene metamaterials (m-MXenes) are developed with a superlattice with alternating MXene and organic layers, reducing RI and inducing multiple light reflections. This approach increases light absorption, inducing 90% photothermal conversion efficiency. The m-MXene is coated onto liquid crystal elastomer (LCE) fibers, as actuating platforms via a dip-coating (m-MXene/aLCE fiber), exhibiting excellent light-driven actuating owing to the synergetic effect of the patterned m-MXene laysers by structural deformation. The m-MXene/aLCE fibers lift ~6,900 times their weight and exhibit a work density 6 times higher than that of human skeletal muscle. It is applied to artificial muscles, grippers, and a bistable structure (a shooting device, and switchable gripper). Our study offers an effective strategy to enhance light absorption in 2D nanomaterials and contributes to advancements in photothermal technologies in various fields.
