Analyses of Impregnation Quality and Mechanical Properties of Radiata Pine Wood Treated with Copper Nanoparticle- and Micronized-Copper-Based Wood Preservatives

In this work, the impregnation quality and mechanical properties of Pinus radiata D.Don treated with different copper nanoparticles (CuNP) solutions (named K1 K2) a commercial preservative (M) were studied. The pine wood was analyzed by two indicators, penetration retention. micro-distribution in qualitatively evaluated SEM-EDS, both samples containing CuNP those preservative. addition, some studied preserved including MOE, MOR hardness. results indicated values ED XRF retention 0.96 kg/m3 0.86 for K2, respectively, 1.01 M impregnated. determined colorimetric test, impregnated (with K1, K2 M) showed 100% penetration. distribution micronized within structure confirmed SEM EDS mapping. properties, reduction MOE reflected all treated. control far superior to slightly samples, no statistically significant differences. On other hand, highest hardness parallel perpendicular grain, revealing that these tend increase Overall, when it comes (M), considerably lower compared wood. Therefore, CuNP-based did not strongly affect
