The results of DSC analysis: effect of electrospinning process and PHB/Coll ratio on PHB melting and degree of crystallinity (χ) (mean ± SD, n = 3-4).
| PHB/Coll (w/w) | T m (°C) | ΔHm (J/g) | χ (%) | |
|---|---|---|---|---|
| PHB powder | 100/0 | 175.4 ± 0.9 | 80.5 ± 1.1 | 55 ± 1 |
| Fibrous mesh | 100/0 | 176.7 ± 0.1a | 94.6 ± 19.2 | 65 ± 13 |
| 70/30 | 173.5 ± 0.9a,b | 45.5 ± 1.7a,b | 45 ± 2b | |
| 50/50 | 171.8 ± 0.1a,b | 27.3 ± 3.9a,b | 37 ± 5a,b |
