| Abstract Scope |
Porous scaffolds are used in many engineering applications such as biomedical implants, aerospace composites, and radioactive waste filters. Their fabrication, specifically the use of irregularly shaped particle frit as a base material, often result in scaffolds that fail to give the structural properties necessary to fulfil their target applications. This project aims to use microspheres as a base material to produce porous scaffolds with microstructures that produce desirable properties when compared to irregular shaped frit. These scaffolds are fabricated using freeze casting, a technique that employs ice crystals to template porous ceramic scaffolds and will be compared to the mechanical properties and microstructure of scaffolds fabricated with irregular shaped frit. Using microspheres produces porous scaffolds with microstructures that have desirable properties when compared to irregular shaped frit. These microsphere-based freeze cast scaffolds can be used to promote cell growth and as filter materials to pick up radioactive waste. |
