Bu çalışmada, kil tabakaları arasında kitosan/benzaldehit modifikasyonu hedeflendi. Kil olarak nano boyuttaki bentonit kullanıldı. İlk olarak kil tabakalarının sürfaktan varlığında açılması sağlandı. Kitosan/benzaldehit modifikasyonu bu tabakalar arasında kimyasal yöntemle gerçekleştirildi. Elde edilen biyokompozitin FT-IR, XRD, TGA ve SEM analiz yöntemleri kullanılarak karakterizasyonu yapıldı. Sonuç olarak, modifiye kitosanın, bentonit tabakaları arasına girerek biyobozunur ve anti kansorejen nanokompoziti sentezlendi.

Biodegradable and anti-carcinogenic chitosan/benzaldehyde modification and preparation of its nanocomposite

Öz

In this study, chitosan / benzaldehyde modification was made between the clay layers. The bentonite clay was used as a nanoscale. First opened in the presence of surfactant in the clay layers was achieved. Chitosan/benzaldehyde modification between these layers was performed by chemical methods. Characterizations of synthesized biocomposite were obtained by FT-IR, XRD, TGA and SEM analysis techniques. As a result, the modified chitosan entering between the layers of bentonite, anti-carcinogenic and biodegradable nanocomposites were synthesized.
