Abstract

Summary: Poly(ε-caprolactone)/Bioactive glass (BG) composites were prepared to study the effects of bioactive glass on mechanical and thermal behavior of poly(ε-caprolactone) (PCL). Composites were fabricated using a solvent casting/sonication technique. Composite characterization was conducted by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and tensile tests. Interphase adhesion between filler and matrix, a prerequisite for good mechanical properties, was evaluated by dynamic mechanical analysis (DMA). The obtained results showed that BG leaded to an acceleration of the composite thermal degradation accompanied by a general enhancement of the mechanical properties.
