Non-templated manufacturing of patterned fluoropolymer membranes via immersion precipitation printing

Additive Manufacturing 2022 Volume 58, Pages 103017

Fluoropolymers are amongst the most common polymers used for the fabrication of filtration membranes. Despite this, commercial production of these membranes remains dominated by simple casting and solvent phase separation. Herein, we show a rapid, simple approach to produce fluoropolymer membranes, with a porous patterned surface, via immersion precipitation printing (ipP). The patterns can act as a permeate spacer, which are traditionally added to a membrane separately to induce turbulent flow and subsequently decreasing membrane fouling. The direct phase inversion of the permeate spacer during membrane production induces a porous morphology. Further, intimate mechanical connection between the membrane surface and…
