Fig. 1: Mechanism of CSAA.
From: Chaperone solvent-assisted assembly of polymers at the interface of two immiscible liquids
a Schematic illustration of the CSAA process. Chaperone solvent γ forms micelles with target polymer X in the oil phase, then the micelles diffuse towards the α-β interface due to the concentration gradient of chaperone solvent γ. Only amphiphilic chaperone solvent γ diffuses across the interface while target polymer X is trapped at the interface, forming the 2D polymer film. Purple entangled line: target polymer X; green species: chaperone solvent γ. b Ternary-composite phase diagram of the mixing solvent system containing toluene/water /DMSO.
