Abstract

Abstract Following pilot testing of the effects of alkaline-based nanoparticles on modern parchment, the treatment was extended to historical parchment. This paper describes the application and impact of calcium hydroxide and calcium carbonate nanoparticles dispersed in (i) propan-2-ol and (ii) cyclohexane on a parchment book cover dated 1570. The cover showed signs of damage resulting from contact with iron gall inks and low pH values (∼4–5). Protocols for the damage assessment of collagen in parchment as developed in the IDAP project (Improved Damage Assessment of Parchment) were used to evaluate the impact of the conservation treatments on parchment. Preliminary results have shown that the application of calcium-based nanoparticles did not produce any adverse effects on the state of preservation of collagen. In addition, positive outcomes emerged: the pH was re-adjusted to a neutral value, a strengthening and consolidation effect was observed, and the nanoparticles exhibited a protective action upon artificial ageing of the treated parchment.

来自NANOforArt项目的见解:钙基纳米颗粒分散体在改善羊皮纸文件保存方面的应用

摘要在对碱性纳米颗粒对现代羊皮纸的影响进行了初步测试后，该处理扩展到了历史羊皮纸。本文描述了分散在（i）丙-2-醇和（ii）环己烷中的氢氧化钙和碳酸钙纳米颗粒在1570年羊皮纸封面上的应用和影响。盖子显示出由于接触铁胆油墨和低pH值（~4-5）而造成的损坏迹象。IDAP项目（改进羊皮纸损伤评估）中制定的羊皮纸中胶原蛋白损伤评估方案用于评估保护处理对羊皮纸的影响。初步结果表明，钙基纳米颗粒的应用不会对胶原的保存状态产生任何不利影响。此外，还出现了积极的结果：pH值被重新调整到中性值，观察到增强和固结作用，纳米颗粒对处理过的羊皮纸的人工老化表现出保护作用。
