The porous bioglass scaffolds with high porosity and interconnectivity and controllable pore size were prepared by using the powder of sol-gel derived bioactive glass-58S as the material and the pre-produced polymer foam as the template. The apparent porosity, crystalline phases, micromorphologies and bioactivity were investigated by using Archimedes drainage method, X-ray Diffraction (XRD), Scan emission Microscope (SEM) and Fourier Transform Infrared Spectroscope (FTIR) techniques. The results show that the apparent porosity of the porous scaffolds can reach about 93% when the materials are dipped once, while the apparent porosity decreases to 80% after dipped twice. The originally formed amorphousphosphorus compounds on the surface of samples are mineralized to hydroxyl-carbonate-apatite (HCA) with increasing dipping time in the SBF solution as the reaction progressed. So it can be concluded that this kind of material has good biomineralization property and bioactivity in SBF solution at the constant temperature of 37℃.
