there Nano crystalline cellulose It has many useful properties, including its high mechanical strength and purity, high crystallinity, biodegradability, and compatibility with a wide range of materials. These properties make nanocrystalline cellulose a promising material for use in the preservation of works of art, particularly in graphic works and documents produced on paper supports, which are widely available in museum collections. Whether it is thin papers, transparencies, gelatin sheets or certain polymers, the materials they are composed of are inherently fragile and often present frequent structural modifications that can cause many problems, especially when the works are manipulated, referenced or exposed.

Remy Dreyfus DesignThe graphic arts heritage restorer and graduate of the National Institute of Photography and the École du Louvre (Paris, France) has succeeded in developing thin, transparent films composed of 100% nanocrystalline cellulose as well as nanocomposites. This makes it possible to play the role of protective covers, reinforcing materials and also fill (gaps). These films can be applied to works of art to repair them but also to protect them from environmental factors such as moisture, UV rays and pollutants. These coatings can help prevent artworks from deteriorating and fading over time.

Therefore, cellulose nanofilms have many advantages, such as:

  • Great intrinsic stability.
  • Great transparency properties.
  • Fineness and great resistance of the material;
  • Good compatibility with worksheets. And
  • Good stability during aging.

In addition, new methods have recently been developed that allow the direct use of Nano-crystalline cellulose gel To consolidate graphic documents, such as repairing tears or strengthening a graphic layer.

Finally, nanocrystalline cellulose can be used as a reinforcing agent in materials used in artwork. Therefore, adding nanocrystalline cellulose to paint or varnish can increase its strength and durability, while maintaining its transparency or color. The life of the artwork is extended by reducing the risk of cracking, chipping, or other forms of damage.

It is clear that the use of nanocrystalline cellulose in the preservation of works of art is very promising, especially through the development of new materials and harmless technologies, which contribute to the preservation of the world's artistic heritage for future generations.
