摘要: Here we report the shape transformation of poly(ethylene glycol)-polystyrene (PEG-PS) polymersomes into ordered inverse morphologies, directed by salt concentration medium and presence azide groups on polymersome surface. The moieties introduced at chain ends PEG blocks induce a difference in hydrodynamic volume hydrophilic domains inner outer side vesicular membrane, allowing control over its spontaneous curvature hence pathway deformation. This simple modification enables access to intricate morphologies which are traditionally only accessible via application complex polymer building blocks.
