Membrane synthesis via thermally induced phase separation: quantifying the shift to a more sustainable design

Abstract

Thermally induced phase separation (TIPS) technique is often employed in membrane manufacturing to create highly porous relatively homogenous membranes. The technique generates porous materials due to a phase separation driven by crystallization or thermodynamic immiscibility. To maintain the use of the technique in the future, the solution chemistry needs to be re-examined to meet the sustainability metrics required for the next generation of membrane design and manufacturing. In this work, we examine TIPS process sustainability and metrics that could be used in future works on the topic.
