The improving effect of nanoparticles on wood dimensional stability is barely known
nowadays. The expected result of the research was the improvement of the dimensional
stability through bulk hydrophobization, as a result of impregnation with hydrophobic SiO2
nanoparticles. Two different wood species, beech (Fagus sylvatica) and scots pine (Pinus
sylvestris) were investigated. Two different treatments with silica nanoparticles were used.
One treatment was a pure emulsion of modified (hydrophobized) silica nanoparticles (carrier …
