Abstract

Ancient architectural color paintings are highly susceptible to outdoor environmental conditions. This study explores the feasibility of fluorinated ethylene vinyl ether (FEVE) composites incorporating TiO₂ and SiO2 nanoparticles (F-T/S) as a protective coating for preservation. Characterization results revealed uniformly dispersed nanoparticles without agglomeration or phase changes. The F-T/S films demonstrated enhanced hydrophobicity, UV resistance, and mechanical strength. Nano-SiO2 and Nano-TiO2 significantly improved water resistance ability and UV durability respectively, and mechanical tests also confirmed good tensile strength and hardness. The composites also exhibited strong antifungal activity against Aspergillus niger, Aspergillus flavus, and Penicillium citrinum species. Applied to surface of model film samples and pigment layer, the composites maintained excellent durability and visual integrity after 480-hour degradation cycles. These findings highlight F-T/S as a multifunctional conservation material, offering simultaneous mechanical reinforcement, environmental protection, and antifungal properties for conservation of heritage paintings.

用多功能复合涂层保护雨花亭彩画

古建筑彩画极易受室外环境条件的影响。本研究探讨了含tio2和SiO2纳米颗粒（F-T/S）的氟化乙烯基醚（FEVE）复合材料作为保护涂层的可行性。表征结果显示纳米颗粒均匀分散，无团聚或相变。F-T/S薄膜表现出增强的疏水性、抗紫外线性和机械强度。纳米sio2和纳米tio2分别显著提高了耐水性和紫外线耐久性，力学试验也证实了良好的抗拉强度和硬度。复合材料对黑曲霉、黄曲霉和柑橘青霉具有较强的抗真菌活性。应用于模型膜样品和颜料层表面，经过480小时的降解循环后，复合材料仍保持了良好的耐久性和视觉完整性。这些发现强调了F-T/S作为一种多功能保护材料，可以同时提供机械加固、环境保护和抗真菌特性，用于文物绘画的保护。

期刊介绍： npj Materials Degradation considers basic and applied research that explores all aspects of the degradation of metallic and non-metallic materials. The journal broadly defines ‘materials degradation’ as a reduction in the ability of a material to perform its task in-service as a result of environmental exposure. The journal covers a broad range of topics including but not limited to: -Degradation of metals, glasses, minerals, polymers, ceramics, cements and composites in natural and engineered environments, as a result of various stimuli -Computational and experimental studies of degradation mechanisms and kinetics -Characterization of degradation by traditional and emerging techniques -New approaches and technologies for enhancing resistance to degradation -Inspection and monitoring techniques for materials in-service, such as sensing technologies
