The average magnetic anisotropy of polystyrene in polymersomes self-assembled from poly(ethylene glycol)-b-polystyrene

Abstract

The magnetic response of polymer vesicles can be studied using magnetic birefringence, but its response is hampered by a large degree of disorder in the polymer membrane. Here we show that a universal effective anisotropy per monomer remains, which can be used to study different polymersome shapes.
