Silk fabrics hold immense historical value as precious legacies left by our ancestors, yet they face significant damage during archaeological excavations, necessitating urgent protective measures. However, The current protective materials can't effectively prevent the degradation of silk fabrics. Nanotechnology has emerged as a promising avenue for the consolidation and preservation of silk fabrics, offering novel concepts and materials. In this study, we propose an innovative and cost-effective method that uses the MOF-818 with a radical scavenging ability to enhance the protection of silk fabrics. The resulting demonstrates that the MOF-818 was the large surface area and porous properties, which exhibited excellent superoxide dismutase (SOD)-like activity at 10 ug/mL. The silk fabrics treated by MOF-818 displays small color difference, reduced the oxidation of functional group and prevents the degradation of silk fabrics. The successful development of this nanocomposite marks a significant advancement in silk protection, opening new horizons for the preservation of silk cultural relics.
丝绸织物作为我们祖先留下的宝贵遗产，具有巨大的历史价值，但在考古挖掘过程中，它们会受到严重的损坏，因此需要采取紧急的保护措施。然而，目前的保护材料并不能有效地防止丝绸织物的降解。纳米技术为丝绸织物的加固和保存提供了新的概念和材料，是一种很有前途的方法。在本研究中，我们提出了一种创新且经济有效的方法，使用具有自由基清除能力的 MOF-818 来增强丝绸织物的保护。结果表明，MOF-818 具有较大的比表面积和多孔特性，在 10ug/mL 时表现出优异的超氧化物歧化酶（SOD）样活性。经 MOF-818 处理的丝绸织物色差较小，减少了功能基团的氧化，防止了丝绸织物的降解。这种纳米复合材料的成功开发标志着丝绸保护的重大进展，为丝绸文物的保护开辟了新的前景。
