The methods of co-electrospinning and surface hydrolysis have been used for improving hydrophilicity of Poly(l-lactide) (PLLA), while most of them resulted in high shrinkage and changed mechanical properties of bulk polymers. In this study, we modify PLLA electrospun scaffolds by grafting chitosan by aminolysis technology. The results showed that the amount of grafted chitosan on fibrous scaffolds...
In this paper, poly (d,l-lactic acid) (PDLLA) incorporated with bioactive β-dicalcium silicate (β-Ca 2 SiO 4 ) powders to prepare composite scaffolds through conventional solvent casting-particle leaching method using sodium chloride as porogen. The pore structures and morphology of the scaffolds were determined by Scanning Electron Microscopy (SEM) and the porosity of the scaffolds...
Composite scaffolds of polyhydroxybutyrate-polyhydroxyvalerate (PHBV) with bioactive wollastonite were fabricated by a compression moulding, thermal processing, and salt particulate leaching method. Structure and mechanical properties of the scaffolds were determined. The bioactivity of the composites was evaluated by soaking in a simulated body fluid (SBF), and the formation of the hydroxyapatite...
