Erk ABSTRACT New ultrafiltration membranes are created by self-assembly of block polymers and non-solvent induced phase separation techniques (SNIPS). Providing a platform with a hierarchical and well- defined porous network, these membranes offer high selectivity and permeability, along with good mechanical responses. It has been proven that SNIPS membranes could exhibit superior performance than the state-of-the-art commercial membranes. However, a major challenge towards the creation of a commercial product is to manufacture SNIPS membranes by continuous casting techniques. Hence, it is necessary to elucidate the fundamental physical principles of SNIPS casting solutions to start building a mass production casting process. It is believed that the SNIPS solutions' flow behavior has a strong correlation with the final morphology of membranes fabricated via roll-to-roll casting techniques. In this proposal, rheometry is introduced as a powerful tool to characterize the SNIPS solutions' flow behavior and to elucidate the structure- properties-performance interrelationships of SNIPS solutions.
