Table 1. Solution Properties of the Cheese Whey (CW)-Derived Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) with 3-Hydroxyvalerate (3HV) Contents of 20 mol % (PHBVCW20), 40 mol % (PHBVCW40), and 60 mol % (PHBVCW60)a.
| solution | 3HV content (mol %) | solid content (wt %) | viscosity (cP) | surface tension (mN/m) | conductivity (μS/cm) | fiber diameter (μm) |
|---|---|---|---|---|---|---|
| PHBVCW20 | 20 | 2 | 216.2 ± 2.4a | 22.1 ± 0.1a | 0.13 ± 0.03a | 2.2 ± 0.2a |
| PHBVCW40 | 40 | 156.8 ± 1.3b | 22.9 ± 0.3b | 0.06 ± 0.01b | 2.2 ± 0.1a | |
| PHBVCW60 | 60 | 171.3 ± 1.1c | 21.9 ± 0.1a | 0.09 ± 0.01a | 2.1 ± 0.2a |
Different letters (a–c) in the same column indicate a significant difference among the samples (p < 0.05).
