“…In order to prepare PEG- b -PS vesicles with high solid content, RAFT dispersion polymerization following PISA was performed, which has been demonstrated to be an effective strategy. − Herein, the degree of polymerization (DP) of the PS block is targeted at 230 to ensure enough thickness of the vesicular membrane. After 12 h of polymerization with 85.6% monomer conversion, the PEG 45 - b -PS 197 vesicles were obtained.…”

Introduction of a fluorine-containing block into block copolymers is an effective method to tune block copolymer nanoassemblies with a microphase-separated structure. However, this microphase-separated structure is difficult to clearly observe due to its nanoscale size. In this work, fluorine-containing ABC triblock copolymer vesicles of poly(ethylene glycol)-block-polystyrene-block-poly(4-vinylbenzyl pentafluorophenyl ether) (PEG-b-PS-b-PVBFP) are synthesized by reversible addition–fragmentation chain transfer (RAFT) polymerization under dispersed condition. Owing to the choice of a suitable degree of polymerization of the three blocks, the synthesized PEG45-b-PS197-b-PVBFP233 vesicles have a relatively large size of around 216 nm and a thin vesicular membrane with a thickness of around 28 nm. Ascribed to the relatively large size of the vesicles and the thin vesicular membrane, it is concluded that the fluorine-containing PVBFP block forms 9 nm columnar microdomains shielded by the PS phase in the vesicular membrane.

“…Different morphologies such as spherical, cylindrical, lamellar and other complicated structures are prepared by bottom-up self-assembly of block copolymers. 1–4 The self-assemblies are widely studied in biological and materials science. For example, amphiphilic block copolymers are self-assembled into vesicles that are extensively studied in controlled drug delivery and therapy.…”
