Melt processing and characterization of tricalcium phosphate filled polybutylene adipate-co-terephthalate/polymethyl methacrylate composites for biomedical applications

摘要

PBAT/PMMA/MA/TCP composites were prepared by melt blending and characterized by FTIR, XRD, SEM and in vitro bioactivity studies using SBF and cell viability tests. SBF studies revealed good bioactivity nature which was observed in SEM and confirmed by EDAX. Cell viability test revealed an excellent viability of squamous cells within 2 h than the control. Soil burial tests of the composites show fast degradation within 50 days under natural conditions. The tensile and hardness properties is marginally increased than that of PBAT/PMMA blend. These biocomposites can be used for the fabrication of medical devices by melt blending and injection molding process.
