Surface modification of wood materials covers various methods to increase durability, performance, aesthetics and lifespan. These techniques, which are widely used in areas such as furniture, structural wood and decoration, are further developed with the innovations offered by nanotechnology. In particular, nanotechnology offers an effective solution in creating stain-proof and hygienic surfaces by applying hydrophobic coatings to wood surfaces, preventing water permeation and extending their lifespan. In this study, three different nanocoating solutions (AS-54, HL-31 and SH-5) were created to increase the hydrophobic properties of wood surfaces and applied to Scots pine (Pinus sytvestris L.), Turkish beech (Fagus orientalis Lipsky) and cedar (Cedar libani A. Rich.) wood species. Then, color, gloss, contact angle (wettability) and FTIR tests of the coated surfaces were performed. Experimental results show that SH-5 nano solution synthesis applied to oriental beech samples gives the best result with a contact angle of 103,51°, creating a hydrophobic (water repellent) and stain-resistant surface. This research highlights the critical role of nanomaterials in protecting wooden surfaces and ensuring hygiene conditions.

Ahşap malzemelerin yüzey modifikasyonu, dayanıklılık, performans, estetik ve kullanım ömrünü artırmaya yönelik çeşitli yöntemleri kapsar. Mobilya, yapısal ahşap ve dekorasyon gibi alanlarda yaygın olarak kullanılan bu teknikler, nanoteknolojinin sunduğu yeniliklerle daha da gelişmektedir. Özellikle nanoteknoloji, ahşap yüzeylere hidrofobik kaplamalar uygulayarak su geçirimini engelleyip ömrünü uzatırken, leke tutmaz ve hijyenik yüzeyler oluşturmada etkili bir çözüm sunmaktadır. Bu çalışmada, Ahşap yüzeylerin hidrofobik özelliklerini artırmak için üç farklı nano kaplama çözeltisi (AS-54, HL-31 ve SH-5) oluşturuldu ve sarıçam (Pinus sytvestris L.), Doğu kayını (Fagus orientalis Lipsky) ve Sedir (C. libani A. Rich.) ağaç türlerine uygulandı. Deney sonuçları, doğu kayını örneklerine uygulanan SH-5 nano solüsyon sentezinin 103,51° temas açısı ile en iyi sonucu verdiğini, hidrofobik (su itici) ve leke tutmaz bir yüzey oluşturduğunu göstermektedir. Bu araştırma, ahşap yüzeylerin korunması ve hijyen koşullarının sağlanmasında nano malzemelerin kritik rolünü vurgulamaktadır.
