Memori Project: Evaluation of Damage to Exposed Organic-Based Heritage Materials and Nanoforart: Evaluation of Nanoparticle-Based Conservation Treatment
Copyright policy )This paper presents preliminary studies and work in progress in the framework of two FP7 projects: MEMORI (Measurement, Effect Assessment and Mitigation of Pollutant Impact on Movable Cultural Assets - Innovative Research for Market Transfer) and NANOFORART (Nano-materials for the conservation and preservation of movable and immovable artworks). One of the aims of the MEMORI project is the determination of threshold levels of damage to exposed organic-based heritage objects as little is known about the impact of organic compounds, especially volatile organic acids, on organic-based cultural objects. In the previous PROPAINT project (Protection of Paintings during Exhibition, Storage Transit) it was recently demonstrated that levels of volatile organic compounds (VOCs) were often much higher in the micro-climate frames used to protect paintings than recommended levels. In this paper, examples will be given of changes observed in varnished strips exposed at selected sites. Studies on the effect on collagen-based materials will also be presented. Techniques used in both projects include Dynamic Mechanical Analysis (DMA), micro-thermal analysis (μ-TA), and atomic force microscopy (AFM). The NANOFORART project explores the effects of using nanoparticle-based conservation treatment on cellulosic and collagen-based cultural materials. It builds on previous work performed on deacidification of canvas paintings using conventional materials. For collagen-based materials, no previous conservation treatment using nanoparticles has been performed on historical parchment or leather objects. Preliminary work is directed at understanding the type of nanoparticles to use to improve the physicochemical state of collagen-based objects.
