Abstract: Acrylic resin Primal SF-016, a conventional polymeric consolidant for mural conservation, exhibits susceptibility to photodegradation under prolonged UV radiation. Ti3C2Tx MXene/SF-016 composites were successfully prepared through a solution blending method. X-ray diffraction (XRD), transmission electron microscopy (TEM), and Raman spectroscopy were used to investigate the structure of Ti3C2Tx MXene/SF-016 composites. The light transmittance, hydrophilicity, and UV-aging resistance were investigated. The microstructures, water vapor permeability, hydrophilicity, reinforcement strength and color differences of the simulated murals before and after consolidation by Ti3C2Tx MXene/SF-016 composites were investigated. The optimized composites demonstrated enhanced hydrophilicity and UV-aging resistance. For the composites with 0.005% and 0.01% Ti3C2Tx MXene, the UV-shielding performance improved 37%—44% while maintaining ＞80% visible light transmittance. After consolidation by Ti3C2Tx MXene/SF-016, the original porous morphology of the murals could be preserved, water vapor permeability, hydrophilicity and the reinforcement strength were improved. Chromatic stability was maintained at Ti3C2Tx MXene concentrations≤0.01%. The results show that Ti3C2Tx MXene/SF-016 composites have significant potential as innovative materials for mural conservation.
