SURFACE MODIFICATION OF SOL-GEL-DERIVED 45S5 BIOGLASS~? FOR INCORPORATION IN POLYLACTIC ACID (PLA)

摘要

Submicron bioactive glass particles are known to produce better composite scaffolds in comparison with larger particles. Surface modification of these submicron particles can result in better dispersion and improved adhesion to the polymeric matrix of the scaffold. This subsequently promotes bioactivity and ensures good mechanical properties of the final framework. In the current study, submicron 45S5 Bioglass~? powder was synthesized via a novel sol-gel route and subsequently, surface functionalized with memacryloxypropyltriethoxysilane. The surface modified bioactive glass was then characterized and the efficiency of this surface treatment was evaluated with PLA providing an appropriate material for fabrication of scaffolds for bone regeneration.
