Abstract
Nanocomposite is new class of polymer composite whish has nanometer-sized dispersion(1–100 nm) and display excellent properties when compared with conventional composites[1-2]. In this study, we prepared bio-nanocomposite based on organically modified enameland chitosan using a solvent solution method. The morphology of Chitosan/ModifiedEnamel bio-nanocomposite were examined by Scanning Electron Microscopy (SEM). Thisstudy focused on the predicting the pH dependent swelling behaviour of a hydrogel. Theswelling characteristics of Chitosan/Modified Enamel bio-nanocomposite were investigatedby swelling experiments. We performed to characterize the swelling behaviour of the inbio-nanocomposite at different pH (3, 4, 7, 10 ve 11) solutions. Chitosan/Modified Enamelbio-nanocomposite reached maximum swelling ratio (%) at pH 11 and the bionanocompositehydrogel swelling ratio was 4734 at 60 minute. The results showed thatthe swelling ratio of Chitosan/Modified Enamel bio-nanocomposite depended on pH.
