Determination of the hydrophilicity/hydrophobicity of AC nanofibers with the technique of CA measurement in concentrations of 14%, 15%, 16%, 17%, and 18%
| Scaffolds (%) | CA (degree) | Free surface energy γSV (mN/m) |
|---|---|---|
| 14 | 9.66±3.36 | 5.12 |
| 15 | 46.96±0.43 | 4.97±0.04 |
| 16 | 44.11±11.27 | 8.55±5.58 |
| 17 | 32.28±3.38 | 6.86 |
| 18 | 20.97±2.19 | 5.99 |
Note: 14%, 15%, 16%, 17%, and 18% are different concentrations of AC drug-loaded nanofibers.
Abbreviations: AC, cellulose acetate; CA, contact angle.
