Abstract
In this work, two systems of mesoporous bioactive glasses (MBGs) with a series of different SiO2:CaO:P2O5 ratios were derived via a sol-gel method involving the usage of block copolymers Pluronic F127 and P123 as templates, respectively. A two-dimensional hexagonal (P6mm) mesoporous structure was obtained in the two systems with a SiO2:CaO:P2O5 ratio of 80:16:4. With the decrease of the SiO2 content, the porous structure of MBGs became less regular, and the BET surface area and the pore volume were also decreased. Mesoporous bioactive glasses from the template F127 displayed a higher degree of bioactivity than those from the template P123, as a result of the existence of more defects on the walls of the mesopores.
