WOODSTOC · WOOD and STOne Conservation by innovative multifunctional nanocomposites based on sustainable matrices

Cultural heritage (CH) is highly valued by 84% of European citizens as it reflects both national and European identities, contributing significantly to the economy through tourism, cultural and preservation activities. However, stone and wood objects of CH value can suffer from severe deterioration, mostly decohesion and biodeterioration, which are predicted to be worsened by climate change. Currently, available methods often fail to meet the requirements that conservation treatments must fulfil. To address this, WOODSTOC will develop novel nanocomposites that, for the first time, simultaneously strengthen both stone and wood objects while offering antimicrobial protection in a manner that is both compatible with the materials and highly durable. This will be achieved by combining three types of nanoparticles (ZnO, Ag2O, carbon quantum dots), having different colours and antimicrobial abilities, with two types of matrices (hydroxyapatite formed in situ for stone, hydroxypropyl cellulose for wood) which are more sustainable compared to existing alternatives. The project outcomes will enable a more efficient and sustainable preservation of our cultural heritage, thus significantly contributing to UN’s Sustainable Development Goals (SDGs), particularly SDG 11.4 (“Strengthen efforts to protect and safeguard the world’s cultural and natural heritage”). The development of new composites in Europe, as opposed to competing countries where research is ongoing, will also increase European competitiveness. Most importantly, WOODSTOC will give the Postdoctoral Researcher the opportunity to deepen and diversify her scientific knowledge and technical competence, thanks to the research and training provided by the two host institutions (one university and one museum, having complementary fields of expertise, mind-sets and facilities), thus achieving the PR’s career development goal to fortify her independence as a researcher.
