Cellulose nanocrystals as consolidant of paper artefacts. A new concept of conservation of Cultural Heritage

A new work from the NanoLeaves Lab in collaboration with colleagues from the University of Rome Tor Vergata, from ENEA – Italian National Agency for New Technologies, Energy and Sustainable Economic Development and from the University of Rome La Sapienza, focuses on the use of sustainable CNCs in paper conservation. The proposed approach is benign for the health of restorers, as CNCs are non-toxic and they are dispensed from water.

CNCs are transparent, mechanically and thermally stable, and act as a protective treatment for paper fibers. Furthermore, we demonstrated for the first time their straightforward removal from paper by hydrogel cleaning.

Simple? Yes. The treatment is so promising that we applied it to the pages of a book dated 1738 from a private collection, with remarkable consolidation results.

The research is presently published on ACS Applied Materials and Interfaces as an ASAP paper in open access form.

Enjoy this new stunning research!
