A low-strength-centrifugation-assisted approach is developed for rapid gelation of Ti₃C₂Tₓ MXene with a very low dispersion concentration (0.5 mg mL⁻¹) into multifunctional 3D architectures. The MXene gels exhibit reconfigurable internal structures and tunable rheological, tribological, electrochemical, infrared-emissive, and photothermal-conversion properties based on pH-induced surface chemistry changes. By using a gel with optimized pH, high lubrication, exceptional specific capacitance (≈635 and ≈408 F g⁻¹ at 5 and 100 mV s⁻¹), long-term capacitance retention (≈96.7% after 10,000 cycles), and high-precision screen- or extrusion-printing into high-resolution anticounterfeiting patterns can be achieved. The MXene gels show excellent performance in semi-solid lubrication, controllable devices, supercapacitors, information encryption, and infrared camouflaging. The gels are prepared by centrifuging aqueous dispersions of Ti₃C₂Tₓ MXene (pH 10, ≥0.5 mg mL⁻¹) at velocity above 400×g for 30 s. The gels have a high water content (>96 wt%) and exhibit excellent rheological, tribological, electrochemical, and photothermal properties. The gels can be used as inks for high-precision printing and as semi-solid lubricants. The MXene gels also show good anti-counterfeiting properties, with high NIR emissivity and light-to-heat conversion efficiency. The gels can be used for screen-printing and extrusion-printing to create high-resolution anticounterfeiting patterns.
