摘要: 疏水材料的研制一直是石质文物保护工作中的难点问题。本工作制备了一种新型疏水金属有机骨架(MOF)材料,即采用氟硅烷修饰含有2-羟基对苯二甲酸桥联配体的Zr-MOF以获得UIO-O-FS材料,并对材料进行了FTIR、X射线衍射、N2吸附-脱附、热重、扫描电镜和透射电镜等表征分析以及抗侵蚀试验。试验结果表明,该材料具有良好的疏水性、固结性、耐酸性和耐盐性,是一种新型石质文物保护材料。

Abstract: The development of hydrophobic materials has always been a difficult issue in the protection of stone cultural relics. In this work, a new hydrophobic metal-organic framework material was synthesized by modifying the Zr-based MOFs containing 2-hydroxyterephthalic acid linkers with fluorosilane to obtain UIO-O-FS material, and characterization tests such as FTIR, X-ray diffraction, N2 adsorption-desorption, thermogravimetry, scanning electron microscope, and transmission electron microscope, as well as erosion resistance tests, were carried out on the material. Based on the results, the material possesses good hydrophobicity, consolidation ability, acid resistance, and salt resistance, and is a new type of stone heritage conservation material.
Keywords: metal-organic framework  UIO-66-OH  hydrophobic  post-synthetic modification  conservation of limestone heritage
