Optimization of Functionalized PVDF Ultrafiltration (UF) Membranes Fabricated by Vapor-induced Phase Separation (VIPS) |
| 초록 |
Membrane separation technology has been convinced as one of the most efficient and least energy-consuming means to address water problems. Fouling is one of the considerable problems of membranes in water treatment applications. The increasing hydrophilicity of the membranes by chemical modification can offer better membrane fouling resistance. Polyvinylidene fluoride (PVDF) is a generally used material for water treatment membranes. 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. |
