| Abstract Scope |
Bone tissue regeneration in hydroxyapatite (HA) based scaffold are limited in their ability to mimic natural bone due to their inability to generate response to load that improves bone regeneration. Piezoelectric based biomaterial composites, which can generate/ transfer bioelectric signals analogous to bone matrix for physiological functions, can overcome this limitation. In this study hydroxyapatite porous (HA)-sodium potassium niobate (NKN) bio-composites are being investigated. The composite architecture, including the connectivity of the three phases (HA, NKN and porosity) is important for effective bone tissue engineering scaffolds. Directional freeze casting is being used to create hierarchical anisotropic porous structures. Results on the effect of the green state processing and sintering parameters on the microstructure and phase distribution will be presented. |
