Murals are one of the precious legacies of our ancestors; however, they face severe damage along with archeological discoveries, which need urgent repair. Nowadays, nanotechnology provides new concepts and materials for the consolidation and protection of murals. In this work, an innovative method for the protection of murals was proposed with graphene-based nanomaterials through strategically synthesizing a polyacrylic acid-functionalized graphene/nano-Ca(OH) material (PAAG@Ca(OH)) by a facile and economic aqueous method. As a result, the nanocomposite PAAG@Ca(OH) was demonstrated with high porosity, strong adsorption, appropriate hydrophilicity, and better permeability compared to the commercial AC33 sample according to the simulated tests. As expected, the nanocomposite PAAG@Ca(OH) displayed a promising application for the reinforcement of murals, which opens up a new avenue for the protection of murals.
壁画是我们祖先留下的珍贵遗产之一；然而，随着考古发现，它们面临着严重的损坏，急需修复。如今，纳米技术为壁画的加固和保护提供了新的概念和材料。在这项工作中，通过一种简便且经济的水相方法，策略性地合成了一种聚丙烯酸功能化的石墨烯/纳米Ca(OH)材料（PAAG@Ca(OH)），提出了一种基于石墨烯基纳米材料的创新壁画保护方法。结果表明，与市售AC33样品相比，纳米复合材料PAAG@Ca(OH)具有高孔隙率、强吸附性、适当的亲水性和更好的渗透性。正如预期的那样，纳米复合材料PAAG@Ca(OH)在壁画加固方面显示出有前景的应用，为壁画保护开辟了一条新途径。
