Development of scaffolds by thermally-induced phase separation from biodegradable poly(3-hydroxybutyrate-co-3-hydroxyvalerate) and poly(butylene succinate)

Abstract:TIPS process followed by freeze-dtying was used to prepare blodegradable and biocompatible matrices from poly(3- hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) containing 5 and 12 wt% of 3-hydroxyvalerate (HV) and poly(butylene succinate) (PBS). 1,4 dioxane (DXN) and tetrahydofuran (THF) were used as solvents. The cloud points of the polymer solutions were determíned by turbidimetry method, to predict the locus of binodal curve in the binary phase diagrams. A multidirectional cooling from ~70ºC to 25ºC, and then… Show more
