Asymmetric disk-shaped Janus micelles form spontaneously and reversibly when simple water-soluble diblock copolymers in aqueous solutions are mixed. The combination of associative and segregative phase separation within one nanostructure results in a disk-shaped micelle with a complex coacervate core and an asymmetric water-swollen corona which is microphase-separated into two distinct domains or faces.
