Abstract
The invention relates to an ordered mesoporous bioactive glass material with apatite nanocrystallines and a method for producing the ordered mesoporous bioactive glass material with apatite nanocrystallines. The molar ratio of the main ingredients of the mesoporous bioactive glass material is that silicon dioxide to calcium oxide to phosphoric anhydride is (60-90):(6-36):(4-5), and an apatite nanocrystalline structure is a nanocrystal with nanopore clustered hydroxyapatite. The material adopts a double-template technology, carbon microspheres are taken as hard templates, a structure-directing agent is taken as a mesoporous template, and a sol-gel method is combined so as to synthesize the material under moderate conditions. The components of the novel mesoporous bioactive glass can be adjusted, a mesostructure is ordered and controllable, the pore diameter can be controlled within the range between 2 nanometers and 20 nanometers, the specific surface area can reach 600square meters/gram, and the pore volume can reach 0.8cubic centimeter/gram. The ordered mesoporous bioactive glass material can be used a support material for bone substituent or repair materials, drug release and tissue engineering.
