Isıl işlemli odunda faz değiştiren malzemelerin kullanımı, odunun termal özelliklerini geliştirmek için yenilikçi bir yol sunarak çeşitli uygulamalarda enerji verimliliğine ve termal konfora katkıda bulunur. Bununla birlikte, kullanılan malzeme ve yöntemlerin dikkatli bir şekilde değerlendirilmesi, bu teknolojinin etkinliğini ve pratikliğini sağlamak için esastır. Faz değiştiren malzemeler (FDM), çeşitli yöntemlerle ısıl işlem uygulanmış oduna entegre edilebilir. Bunun için birçok yöntem vardır. Bu yöntemlerden biri FDM’nin oduna emprenyesidir. Diğer yöntem ise FDM’nin odun yüzeyinde üst yüzey işlemi veya cila olarak uygulanması. Bu çalışmada faz değiştiren malzeme olarak 1-tetradekanol (TD) kullanılmış ve termal olarak modifiye edilmiş dişbudak ağacı (TMA) üzerindeki etkinliği araştırılmıştır. TMA, enerji depolama uygulamalarında ısı kaybını en aza indirmek için gerekli olan daha iyi ısı yalıtım özelliklerine sahiptir. Bu amaçla, termal olarak modifiye edilmiş dişbudak odunundan (TMA) TD sızıntısı, sızıntı testi ile test edilmiştir. Örnekler diferansiyel taramalı kalorimetri (DSC), termogravimetrik analiz (TGA), fourier transform kızılötesi spektroskopisi (FTIR) ile incelendi. Sonuçlara göre sızıntı testinde az miktarda sızıntı vardı. TGA analizi, TD/TMA'nın, emprenyesiz ısıl işlemli onunda (TMA) 800°C'de bıraktığı %18.20'lik kalıntıya kıyasla %16.30'luk daha düşük bir kalıntı bıraktığını gösterdi.

The use of phase change materials in thermally modified wood presents an innovative way to enhance the thermal properties of wood, contributing to energy efficiency and thermal comfort in various applications. However, careful consideration of the materials and methods used is essential to ensure the effectiveness and practicality of this technology. Phase change materials (PCM) can be integrated into thermally modified wood through various methods. One common method is impregnation, where the PCM is infused into the wood structure. Another method could be the application of PCM in coatings or finishes applied to the wood surface. In this study, 1-tetradecanol (TD) was used as a PCM and its effectiveness on thermally modified ash wood (TMA) was investigated. TMA has better thermal insulation properties, which are essential in energy storage applications to minimize heat loss. For this purpose, the leaching of TD from TMA was examined. Differential scanning calorimetry (DSC), thermogravimetric analyses (TGA), fourier transform infrared spectroscopy (FTIR) were examined. According to the results, there was a small amount of leakage in the leakage test. TGA analysis showed that TD/TMA left a lower residue of 16.30% at 800°C compared to the residue of 18.20% left by untreated thermally modified wood (TMA).
