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.
