Abstract EN
Hydroxyapatite is a biocompatible ceramic and reinforcing material for bone implantations.
In this study, Starch-chitosan hydrogel was produced using the oxidation of starch solution and subsequently cross-linked with chitosan via reductive alkylation method (weight ratio (starch/chitosan): 0.38).
The hydroxyapatite micropowders and nanopowders synthesized by sol-gel method (10, 20, 30, 40 %W) were composited to hydrogels and were investigated by mechanical analysis.
The results of SEM images and Zetasizer experiments for synthesized nanopowders showed an average size of 100 nm.
The nanoparticles distributed as uniform in the chitosan-starch film.
The tensile modulus increased for composites containing hydroxyapatite nano-(size particle: 100 nanometer) powders than composites containing micro-(size particle: 100 micrometer) powders.
The swelling percentage decreased for samples containing hydroxyapatite nanopowder than the micropowders.
These nanocomposites could be applied for hard-tissue engineering.
