description The aim of this research was to realize new potential wood preservatives against fungaldecay, with low environmental impact and well fixed into the wood.Pinus sylvestris L. wood samples were impregnated by silica xerogels functionalized withamino groups able to link copper through coordinative interactions. In this study tetraethoxysilane(TEOS) and 3-aminopropyltriethoxysilane (APTES), in different ratios, and linked with copper ornot, were utilized to impregnate wood samples, in order to evaluate the factors responsible for theefficacy against the brown rot Coniophora puteana. The fixation to the wood was evaluated throughthe leaching procedure (EN 84) and the variation on the effectiveness against this fungus.The sol-gel processes TEOS/APTES, ratio 1:1, with or without copper, leached or notleached, showed a good effectiveness against fungus C. puteana.
