Characterization of SF/PLCL nanofibrous scaffolds of different weight ratios.

Notes: (A) Representative scanning electron microscopy images of SF/PLCL nanofibrous scaffolds of different weight ratios: pure SF, SF/PLCL (75/25), SF/PLCL (50/50), SF/PLCL (25/75), and pure PLCL. Scale bars: 20 μm. (B) Atomic force microscopy images of SF/PLCL nanofibrous scaffolds of different weight ratios. The roughness value Ra represents the average distance between the surface and the mean line from the recordings at each point. The roughness value Ra represents the average distance between the surface and the mean line from recordings at each point. (C) Representative images of water contact angle of SF/PLCL nanofibrous scaffolds of different weight ratios at 15 seconds. (D) Water contact angle of SF/PLCL nanofibrous scaffolds of different weight ratios. (E) Tensile strength of SF/PLCL nanofibrous scaffolds of different weight ratios.

Abbreviations: PLCL, poly(lactide-co-ε-caprolactone); SF, silk fibroin.
