摘要

摘要微纤化纤维素(MFC),通常被称为纳米纤维素,是一种新兴的保护材料,在广泛的保护处理中具有巨大的应用潜力。由于其透明性和机械强度的特性,当薄组织可能不合适时,纳米纤维素膜提供了新的潜力。然而,当水或水性粘合剂应用于纳米纤维素时,它会失去稳定性并变得浆状,这使得实际使用存在问题。此外,纳米纤维素膜在干燥时会收缩,导致平面变形。由于这些原因,迄今为止,与纳米纤维素一起使用的粘合剂在已发表的处理中受到限制。对本研究中使用的纳米纤维素膜进行了表征,并进行了膨胀和收缩测试,以更好地了解引入水和乙醇时纳米纤维素膜的反应。还探讨了以可再润湿形式使用纳米纤维素膜的潜力。结果发现,当引入水时,纳米纤维素膜的表现与日本组织不同。当引入水时,每个纳米纤维素膜都膨胀了,但纳米纤维素膜收缩了11 % 从干燥时的初始尺寸,而日本组织恢复到其初始尺寸。建议采用实用的技术,通过选择粘合剂制作可再润湿的纳米纤维素膜。值得注意的是,用甲基纤维素和明胶制备的可再润湿纳米纤维素膜显示出有希望的初步结果。

Some Practical Aspects of Nanocellulose Film: Characterization, Expansion and Shrinking Tests, and Techniques to Create Remoistenable Nanocellulose
Abstract Microfibrillated cellulose (MFC), commonly referred to as nanocellulose, is an emerging conservation material with significant potential for application in a wide range of conservation treatments. Due to its properties of transparency and mechanical strength, nanocellulose film offers novel potential when thin tissues may not be suitable. However, when water or aqueous adhesives are applied to nanocellulose, it loses stability and becomes pulpy, making practical use problematic. Additionally, nanocellulose film can shrink upon drying, causing planar deformation. For these reasons, adhesives used with nanocellulose are limited in published treatments to date. The nanocellulose film used in this study was characterized and expansion and shrinking tests were conducted to better understand how nanocellulose film reacts when water and ethanol are introduced. The potential of using nanocellulose film in a remoistenable form is also explored. Results found that nanocellulose film behaved differently than Japanese tissue when water was introduced. While each expanded when water was introduced, the nanocellulose film shrunk 11 % from its initial size when dry, whereas the Japanese tissue returned to its initial size. Practical techniques are recommended to create remoistenable nanocellulose film with a selection of adhesives. Notably, remoistenable nanocellulose films created with methylcellulose and gelatine showed promising initial results.
