health but have a negative effect on aquatic living organisms. For this reason, researchers have been focusing on the using of
nano-sized chemical substances in wood preservation. In this study, the effects of nano-sized oxide-based Magnesium oxide,
Zinc oxide, Aluminum oxide, Titanium oxide and nano-clay and their secondary impregnation with PMMA (Poly Methyl
Methacrylate) on the wood material were investigated. Wood samples were prepared from sapwood of Scots pine (Pinus
sylvestris L.). Nano-sized substances except for nano-clay were prepared at 0.5% concentration and dissolved in acetone by using
Ultrasonic mixture while nano-clay was prepared at the concentation of 5, 10 and 15%. The impregnation process was applied
on all samples which have dimensional 5 x 15 x 30 mm (RxTxL) under vacuum (600 mmHg) for 20 min. Then samples were
submerged into solutions for 20 min at atmospheric pressure. The effect of nanoparticles on the physical properties of wood such
as water absorption, tangential swelling, water repellent efficiency and anti-swelling efficiency was determined. According to
results, nano-oxides and nano-clay which containing PMMA were had successful results, compared to control, where water
absorption rate decreasing by 25% approximately than in control samples.
