Preparation of P3HB4HB/(Gelatin + PVA) Composite Scaffolds by Coaxial Electrospinning and Its Biocompatibility Evaluation

Figure 6

Scanning electron microscopy and transmission electron microscopy of the P3HB4HB/(GEL + PVA) scaffolds. (a, d) GEL : PVA = 0.6 g : 0.2 g; (b, e) GEL : PVA = 0.4 g : 0.4 g; (c, f) GEL : PVA = 0.2 g : 0.6 g. (g, h, i) GEL : PVA = 0.2 g : 0.6 g for the scaffolds not soaked in water, soaked for 24 h, and soaked for 48 h.
