原始语种摘要: In this study, recycling of eggshell, which possesses valuable biominerals was utilized for production of nanocrystalline hydroxyapatite powder. Hydroxyapatite was then converted into 3D porous scaffolds by eco-friendly method. For enhancing the mechanical resistance and improving the biodegradability of HA porous scaffold CMC was used to coat the scaffolds with different concentration (0.5, 1.0, 1.5, 2.0% w/v) via infilteration method. The produced carboxymethyl cellulose / hydroxyapatite (CMC/HA) scaffold composites were evaluated for biomedical applications. The results revealed that the compressive strength of CMC/HA composite scaffolds increases with the increase in the CMC content up to 1.5% w/v. Furthermore, the results obtained from thin film XRD, SEM and EDS analysis after...
