Improvement of the mechanical properties of the porous spherical BCP granules by PVA coating |
| 초록 |
Using Poly(ε-Caprolactone)(PCL) as pore-forming agent, Porous spherical BCP granules was fabricated by taking advantage of formation of spherical shape drop of a trickling liquid or slurry. After that, these granules were burnt out to remove polymer and sintered at 1300℃ by microwave sintering. For overcoming the disadvantage of weak mechanical properties of porous BCP granules, it was coated by polyvinyl alcohol (PVA) which is a kind of biodegradable polymer and whose degradation rate is fast. The morphology as well as the characterization of granules with their microstructure and porosity was studied depending on PVA coating time. The mechanical properties of the PVA-coated porous spherical BCP granules were also evaluated. Furthermore, the cell viability and cell attachment of BCP granules were performed using osteoblast like MG-63 cells. |
