a A schematic mechanism of the formation of PILCNx-PDDA ATPS. b Chemical structures of control polymers (top row: PILs, bottom row: PDDA, PAE and PTMAC); PILs aqueous solutions (1 mL) were mixed with PDDA, PAE, PTMAC (1 mL), respectively; phase status of the mixture was determined by naked eyes (Supplementary Fig. 8) and optical microscopy (Supplementary Fig. 9). Note: solid and dash lines indicate the formation of ATPS and homogeneous solution, respectively.
