摘要: This chapter reports the emulsion freezing/freeze-drying technique for formation of three-dimensional porous scaffolds bone tissue engineering applications. Poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV), which is a natural, biodegradable polymer, was used as main polymer fabricating various scaffolds. Nano-sized hydroxyapatite (HA), widely bioceramic, incorporated in order to obtain bioactive (i.e., osteoconductive) composite The focused two areas: (1) investigations into scaffold fabrication using and influence processing parameters on PHBV scaffolds, HA/PHBV HA-containing PHBV/PLLA blend-based scaffolds; (2) evaluation different terms their structure, porosity, pore size, crystallinity, compressive mechanical properties, vitro biodegradation behavior biological performance.
