SYNTHESIS AND CHARACTERIZATION OF BIONANOCOMPOSITES BASED ON CHITOSAN / MODIFIED ENAMEL
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 enamel
and chitosan using a solvent solution method. The morphology of Chitosan/Modified
Enamel bio-nanocomposite were examined by Scanning Electron Microscopy (SEM). This
study focused on the predicting the pH dependent swelling behaviour of a hydrogel. The
swelling characteristics of Chitosan/Modified Enamel bio-nanocomposite were investigated
by swelling experiments. We performed to characterize the swelling behaviour of the in
bio-nanocomposite at different pH (3, 4, 7, 10 ve 11) solutions. Chitosan/Modified Enamel
bio-nanocomposite reached maximum swelling ratio (%) at pH 11 and the bionanocomposite
hydrogel swelling ratio was 4734 at 60 minute. The results showed that
the swelling ratio of Chitosan/Modified Enamel bio-nanocomposite depended on pH.
