Abstract

Natural polysaccharides are environmentally friendly, renewable, biodegradable, fairly inexpensive materials. Performance properties of these materials can be altered by some chemical modifications such as crosslinking and hydrophobic substitution. Crosslinking creates intramolecular and intermolecular ether and ester bonds at random sites in sequential polysaccharide chains. Thus, while the resistance of the materials obtained against acidic environment and heat increases, their viscosity and solubility decreases. Genipin, a natural compound found in Gardenia fruit extract, is generally preferred as a crosslinker because it is non-toxic. In this study, it is aimed to prepare and characterize boron-doped complexes of unmodified starch and starch modified by crosslinking with genipin. For this purpose, scanning electron microscope, X-ray diffraction, Fourier transform infrared spectroscopy, thermogravimetric analysis methods were used and solubility tests were also performed for the obtained powder complexes.

Özet

Doğal polisakkaritler; çevre dostu, yenilenebilir, biyobozunur, oldukça ucuz malzemelerdir. Performans özellikleri çapraz bağlanma ve hidrofobik sübstitüsyon gibi bazı kimyasal modifikasyonlar ile iyileştirilebilir. Çapraz bağlanma ile ardışık polisakkarit zincirlerinde rastgele bölgelerde molekül içi ve moleküller arası eter ve ester bağları oluşur. Böylece elde edilen malzemelerin asidik ortama ve ısıya karşı dirençleri artarken, viskozite ve çözünürlükleri azalır. Gardenya meyve özünde bulunan ve doğal bir bileşik olan genipin genellikle toksik özellik göstermediği için çapraz bağlayıcı olarak tercih edilmektedir. Bu çalışmada; genipin ile çapraz bağlanarak modifiye edilmiş nişasta ve modifiye edilmemiş nişastanun bor katkılı komplekslerinin hazırlanması ve karakterizasyonlarının yapılması amaçlanmıştır. Bu amaçla taramalı elektron mikroskopu, X-ışınları kırınımı, Fourier dönüşümlü kızılötesi spektroskopisi, termogravimetrik analiz yöntemleri kullanılmış ve elde edilen toz halindeki kompleksler için çözünürlük testleri de gerçekleştirilmiştir.
