Nanostructured materials for durability and restoration of wooden surfaces in architecture and civil engineering

TL;DRAbstract

ABSTRACT: The present paper addresses to the latest technological innovations concerning nanostructured-materials, their wood surface protection functions, and describing the potential usage in the field of architecture, civil engineering and cultural heritage. The research briefly describes the existing nanomaterials, their classification and compatibility with the different wooden species. The technology used in this study is water soluble and water-borne organ-functional silane system which desires small depth of penetration by controlled molecular dimension. Defining operative procedures of application with the aim of testing the depth of penetration and the efficacy of the consolidation we find that a novel impregnation system for wooden surfaces could increase durability properties. Additionally, nanoparticles of silver and copper have extremely large relative surface area, increasing their contact with bacteria or fungi, and improving bactericidal and fungicidal effects by adver
