Development of Vapor-induced Phase Separation (VIPS)-derived Functionalized PVDF Ultrafiltration (UF) Membranes |
| 초록 |
Membrane separation has been convinced as one of the most efficient and least energy-consuming means to address water problems. Fouling is one of the significant problems of membranes in water treatment. The increasing hydrophilicity of the membranes by chemical modification can offer better fouling resistance. Polyvinylidene fluoride (PVDF) is a commonly used material for water treatment. However, it is not easy to control the chemical reaction to modify PVDF in its hydrophilicity. In this study, the functionalized PVDF (PVTD) was synthesized by the dechlorination of P(VDF-CTFE). The acquired PVTD has enriched double bonds, giving rise to postsynthetic modifications after fabrication of the UF membranes. We performed the optimization studies for the fabrication of PVTD UF membranes in controlling its morphology. The resulting PVTD UF membranes were chemically modified for enhanced hydrophilicity. The modified PVTD UF membranes were applied for pure water flux and antifouling tests. |
