Preparation of nanofibrous composite membranes in various ways for different combinations of plasma and chemical methods.
| Abbreviation of the Sample | Plasma Modification | Chemical Modification | UV Irradiation |
|---|---|---|---|
| P0* | - | - | - |
| P1 | 5 min Plasma + 20 min exposed to atmosphere | Immersed into NaOH for 24 h | - |
| P2 | 5 min Plasma + 20 min exposed to atmosphere | Immersed into solution E for 2 days | - |
| P3 | 5 min Plasma + 20 min exposed to atmosphere | Immersed into NaOH for 24 h and solution E for 2 days | - |
| P4 | 5 min Plasma + 20 min exposed to atmosphere | Immersed into NaOH for 24 h and solution E for 2 days | 4 min under UV light |
P0* is a neat PVDF/PAN membrane without any post-treatment.
