Extended Data Fig. 4: Containers used for the preparation of macroscopic scale ATPS-supported membranes.
From: Large-area, self-healing block copolymer membranes for energy conversion
a) Schematic illustrating how elongated cells with slanted floor make it possible to control membrane area by varying the position of the ATPS interface. b) ATPS-supported membrane formed by BCP1 and BCP2 using an elongated cell with slanted floor. The displaced toluene solution is floating on top of the PEO phase while a membrane is formed at the PEO/DEX interface. c) 3D rendering of the spiral set-up with slanted floor that allowed to form BCP membranes of up to 8 cm2 surface area. d) 3D rendering of the set-up with internal supporting pillars and slanted floor used to form membranes with 10 cm2 surface-area.
