Direct ink writing of dehydrofluorinated Poly(Vinylidene Difluoride) for microfiltration membrane fabrication

Journal of Membrane Science 2021 Volume 632, Article 119347

Here, a hybrid process for the fabrication of dehydrofluorinated PVDF (dPVDF) microfiltration (MF) membranes is presented. dPVDF was fabricated through the bulk modification of PVDF using ethylenediamine. To produce inks for direct ink writing (DIW), the dPVDF was dissolved in N,N-dimethyacetamide along with a pore-forming agent, poly(vinyl pyrrolidone) (PVP) (5–30 wt%, relative to dPVDF concentration). Membranes were produced by direct ink writing of the inks into continuous films – followed by non-solvent induced phase separation (NIPS). Attenuated total reflectance – Fourier transform infrared (ATR-FTIR) and Raman spectroscopies confirmed alkene moieties within the dPVDF polymer, resulting from the dehydrofluorination process. The…
