| Abstract
| - Hierarchically porous bioactive glass (CaO−SiO2−P2O5) scaffolds have been prepared by using nonionicblock copolymer EO20PO70EO20 (P123) and polyurethane (PUF) as cotemplates. It exhibits a hierarchicalstructure with interconnected macropores (about 200−400 or 500−700 μm), which provide the potentialfor tissue ingrowth and the neovascularization, and uniform mesopores (3.68 nm), which cause an increasein the specific surface area and enhanced bioactivity and release of ionic products. The orderedhierarchically porous scaffold has the advantages of both mesoporosity and macroporosity, which mayfind potential applications in tissue engineering and drug storage.
