Giant tubular and toroidal vesicles from self-assembled triblock copolymer–polyaniline complexes in water

Abstract

An ABA type amphiphilic triblock copolymer was synthesized via ATRP and sulfonation. New self-assembled morphologies such as toroidal vesicles, giant tubular vesicles, and perforated spherical vesicles were observed from triblock copolymer–polyaniline complexes in water. The mechanism of morphology transformation at different compositions was discussed.
