Fabrication of Hierarchically Porous Bioactive Glass Ceramics

Article Preview

Abstract:

Hierarchically 3D porous bioactive glasses (BGs) with various combination of both pore sizes and pore structures have been produced by multi-polymer templating, such as amphiphilic block copolymers, poly urethane (PU) forms, poly styrene (PS) beads, or methyl cellulose (MC), sol-gel method, evaporation-induced self-assembly process, and rapid prototyping technique. The amphiphilic block copolymers used for producing the meso pores into the BGs, which induces large specific surface area and subsequently carries with good bone-forming bioactivity of BGs. Each poly urethane form, poly styrene bead, and methyl cellulose adapted for the fabrication of macro pores. The rapid prototyping (RP) techniques introduced to produce 3D BGs scaffolds with giant pores.
