Fabrication and characterization of poly(3-Hydroxybutyrate) gels using non-solvent-induced phase separation |
초록 |
Poly(3-hydroxybutyrate) (PHB) is a polyester produced by micro-organisms, and it has become one of the most interesting biomaterials owing to its excellent biodegradability and biocompatibility. In this study, PHB oragnogels were produced via NIPS(non-solvent-induced phase separation) using Chloroform as a solvent and THF as a non-solvent. Applying solvent exchange and freeze-drying processes to the as-produced organogels allowed fabrication of nanofibrous PHB monoliths with high porosity. Conformational changes of PHB chains during gelation were monitored in situ by time-dependent infrared spectral (IR) measurements. The scaffold were characterized using scanning electron microscopy (SEM), differectial scanning calorimetry (DSC) and universial testing machine (UTM). |
