Selüloz ve soya proteini
izolatının harman çözeltileri, bir amin/tuz çözücü sistemi kullanılarak
hazırlandı. Gama ışınıyla ışınlanan çözeltilerden harman filmlerin oluşturulmuş
ve ışınlanmamış filmlerden daha kararlı moleküler ağa sahip oldukları
gözlenmiştir. Işınlama bağlı olarak, kızılötesi spektroskopi ile analiz edilen
iki polimer arasındaki etkileşimler değişti ve yayıldı. Termal analiz,
ışınlanmış ve ışınlanmamış çözeltilerden oluşturulan filmler arasında küçük
termal kararlılık farkları gösterdi. 10 kGy ışınlama dozu uygulanan
solüsyonlardan elde edilen filmler kopmada daha yüksek uzama göstermiştir.
Dahası, filmlerin şeffaflıkları azaldığı gözlendi. Şeffaflıklarındaki değişime
rağmen, filmler, gama ışımasının moleküler yapı üzerindeki etkisi dolayısıyla
daha az su emdiler.

Blend Films of Cellulose and Soy Protein Isolate Prepared from Gamma Irradiated Solutions

Öz

Blend solutions of cellulose and soy protein isolate were prepared by utilizing an amine/salt solvent system. The solutions were gamma irradiated before casting blend films that have more stable molecular network than the ones cast from non-irradiated solutions. Due to irradiation, the interactions between the two polymers altered and shifted that were analyzed by infrared spectroscopy. The thermal analysis showed small differences of thermal stability between the films formed from irradiated and non-irradiated solutions. Up to 10 kGy irradiation dose on the solutions, the resulting films exhibited higher elongation at break. Furthermore, their transparency lowered. Despite their transparency, the films absorbed less water indicating the effect of gamma irradiation on the molecular structure.
