Paper and cellulose-based materials are known for their sensitivity to humidity, which can create stresses among fibres and increase fragility. More importantly, humidity can lead to the formation of mould and stains, compromising both aesthetic value and long-term preservation, particularly for historical documents and books. This study explored the application of in situ prepared Zeolitic Imidazolate Framework (ZIF-8), a zinc-based MOF, on paper as a potential antimicrobial material. Hand-made and commercially printed papers were tested to assess the effective deposition and formation of the ZIF-8 network, with a focus on both visual appearance and physicochemical characteristics. X-ray fluorescence and diffraction, infrared spectroscopy, and scanning electron microscopy analysis confirmed the successful formation of the ZIF-8 network in all papers. The Zn content varied, as expected, depending on application time and paper characteristics. All treated papers exhibited minor variations in brilliance and showed slightly increased rigidity. The formation of white spots linked to Zn accumulation was observed, particularly in printed books where colourimetric and microscopic variations were more pronounced.
纸质和纤维素基材料以其对湿度的敏感性而闻名，湿度会在纤维间产生应力并增加脆性。更重要的是，湿度会导致霉菌和污渍的形成，损害美学价值和长期保存效果，尤其是对于历史文献和书籍。本研究探索了原位制备的沸石咪唑酯骨架（ZIF-8，一种锌基金属有机框架材料）作为潜在抗菌材料在纸张上的应用。对手工纸和商业印刷纸进行了测试，以评估ZIF-8网络的有效沉积和形成情况，重点关注外观和物理化学特性。X射线荧光和衍射、红外光谱以及扫描电子显微镜分析证实了所有纸张中ZIF-8网络的成功形成。正如预期的那样，锌含量因施加时间和纸张特性而异。所有处理过的纸张在光泽度上都有轻微变化，并且刚性略有增加。观察到与锌积累相关的白点形成，特别是在印刷书籍中，比色和微观变化更为明显。
