Nano-Sustainable Protective System to Control Biological Colonization For Wood Heritage

Wood is highly susceptible to the damaging effects of biological agents. Consequently, there is a growing interest in protecting wood and wood artworks using environmentally friendly preservatives. The objective of this paper was to study the effectiveness of a nano/siliconate impregnation system for wood protection against wood decay fungi. The study was conducted on samples of Pinus ponderosa. The modifiers or protective agents used included siliconates and nanoparticles. The impregnating agent was applied using a brush, treating the solution as a wood stain. To analyze the protective capacity of the treatment against biodeterioration, the decay resistance test was conducted by exposing the samples to two fungal species, brown rot and white rot, for 16 weeks. The results showed that wood treated with nano/siliconate exhibited excellent resistance to decay. It is worth mentioning that synergistic effects were observed when siliconate and nanoparticles were mixed. Additionally, the impregnant was easy to apply, making it suitable for use on various wood objects and providing the necessary versatility for the protection of heritage wood.
