Supramolecular Self‐Assembly of Giant Polymer Vesicles with Controlled Sizes

Abstract

An ill-defined hyperbranched multiarm copolymer (see picture) with a high hydrophilic fraction (>60 %) self-assembles in water to form giant polymer vesicles (branched polymersomes). The size of the branched polymersomes can be easily controlled by adjusting the hydrophilic fraction of the copolymer, with the average diameter of the larger branched polymersomes exceeding 100 μm.
