Abstract

Wood materials as renewable biodegradable green biomaterials are used in many applications such as furniture, composite materials, construction, interior design, building etc. However, wood materials have some disadvantageous which are low dimensional stability and biological resistance. These undesired properties restrict end-use potential of wood materials. Various modification techniques have been developed to enhance its end-use performance properties. In this work, wood materials were chemically modified with poly(ε-caprolactone) (PCL) which is one of the most promising synthetic biodegradable polymers. Dynamic mechanical thermal analysis (DMTA) and thermogravimetric analysis (TGA) were carried out to evaluate thermal characteristics of the wood materials. Storage modulus and loss modulus values were determined with DMTA, while thermal stability and weight loss were studied with TGA. The findings of this present work showed that the chemical modification of the wood materials by PCL affected the thermal characteristics.

Özet

Yenilenebilir biyobozunur yeşil biyomalzeme olarak ahşap malzemeler birçok uygulama alanında kullanılmaktadır. Bunlara örnek olarak; mobilya, kompozit malzemeler, konstrüksiyon, iç mimari uygulamalar, yapı vb. verilebilir. Pozitif özelliklerinin yanında ahşap malzeme bazı dezavantaj sayılabilecek özellikleri de bünyesinde barındırmaktadır. Bunlar düşük boyutsal stabilite ve biyolojik dayanımdır. Arzu edilmeyen bu özellikler ahşap malzemelerin potansiyel uygulama alanlarını kısıtlamaktadır. Ahşap malzemelerin son kullanım performans özelliklerini geliştirmek için çeşitli modifikasyon yöntemleri geliştirilmiştir. Bu bilimsel çalışmada, çeşitli ahşap malzemeler en çok gelecek vadeden sentetik biyobozunur polimerlerden birisi olan poli(ε-kaprolakton) (PCL) ile kimyasal olarak modifiye edilmiştir. Ahşap malzemelerin termal karakteristiklerini ortaya koymak için dinamik mekanik termal analizler (DMTA) ile termogravimetrik analizler (TGA) gerçekleştirilmiştir. DMTA ile ahşap malzemelerin storage modulus ve loss modulus değerleri belirlenirken, TGA ile termal stabilitesi ve ağırlık kayıpları tespit edilmiştir. Bu araştırma sonucu elde edilen veriler göstermiştir ki, PCL ile yapılan kimyasal modifikasyon ahşap malzemelerin termal özelliklerini etkilemiştir.
