Most of the artworks stored in museums are often kept in inappropriate climatic and environmental conditions that facilitate the formation and growth of microorganisms, such as fungi, which are responsible for many types of biodegradation phenomena. To mitigate and prevent these deteriorative processes, functionalized packaging materials can be used for the storage and handling of artworks. The aim of this study was to develop a potential anti-biodeterioration coating suitable for packaging purposes. TiO and ZnO doped with different amounts of Ag (0.5 wt%, 1 wt%, and 3 wt%) were synthesized and dispersed in polyvinyl alcohol (PVA) and acrylic resin (Paraloid B72), then applied on different types of packaging materials (cellulose and the high-density spunbound polyethylene fiber Tyvek, materials that are frequently used as packaging in museums). Analytical investigations (SEM/EDS, Raman, FTIR, and XRD) were employed to assess dispersion on the packaging material. Furthermore, resistance against biodeteriogens was assessed using sp., a bioluminometer, to define the biocidal efficacy.
大多数存放在博物馆的艺术品往往保存在不适当的气候和环境条件下，这有利于微生物的形成和生长，如真菌，它们会引发多种生物降解现象。为了减轻和防止这些变质过程，可使用功能化包装材料来储存和搬运艺术品。本研究的目的是开发一种适用于包装用途的潜在抗生物降解涂层。合成了掺杂不同量Ag（0.5 wt%、1 wt%和3 wt%）的TiO和ZnO，并将其分散在聚乙烯醇（PVA）和丙烯酸树脂（Paraloid B72）中，然后涂覆在不同类型的包装材料上（纤维素和博物馆常用作包装材料的高密度纺粘聚乙烯纤维特卫强）。采用分析研究方法（扫描电子显微镜/能谱仪、拉曼光谱、傅里叶变换红外光谱和X射线衍射）来评估在包装材料上的分散情况。此外，使用 sp.、生物发光计评估对生物降解剂的抗性，以确定杀菌效果。
