Notes:
In this study, the bioactive composites based on β-tricalcium phosphate (β-TCP),bioglass (BG) and poly lactic acid (PLA) were prepared. The microstructure, degradability andreaction products of the scaffold soaked in a simulated body fluid (SBF) at 36.5℃ for different dayswere characterized through scanning electron microscopy (SEM), energy-dispersive X-ray analysis(EDS), X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FT-IR) and inducedcoupled plasma spectroscopy (ICP). The weight loss and strength decrease with the time were tested.The results showed that at the same porosity, the degradability of the scaffold samples decreased asfollowed: β-TCP/BG/PLA〉β-TCP/BG〉β-TCP.The materials had highly bioactive responseability to the Simulate Body Fluid (SBF) and promptly induced a bone like HA layer on the surfaceof the scaffolds when immersed in the SBF
