metadata.name: dc.description.abstract
metadata.value: Hybrid membranes based of polyphenylene oxide matrix and star macromolecules (up to 5 wt%) containing six
  polystyrene and six poly-2-vinylpyridine arms attached to a common fullerene C60 center were prepared and
  successfully used for pervaporation separation of acetic acid – water mixtures. The peculiarities of the hybrid
  membrane structure and properties were studied by small-angle neutron scattering in two states (dry and swollen
  in deuterated acetic acid). It was established that star macromolecules are non-uniformly distributed in the
  matrix and form aggregates; they increase in the size up to ~60% during swelling of membranes in deuterated
  acetic acid. In pervaporation, the total flux through the membrane rises with increasing both the star macromolecule
  content in membrane and water concentration in the feed. Separation factor reaches its greatest value
  when the hybrid membrane contains 5 wt% star macromolecules.
