摘要：

Two novel methods for imparting magnetic properties to the hollow polyelectrolyte capsules were proposed. The first one includes the impregnation of the capsules with pre-formed Fe3O4 magnetite nanoparticles; the second approach is based on selective synthesis of magnetic Fe3O4 inside the polyelectrolyte capsules filled with polycations. Synthesized Fe3O4 core/polyelectrolyte shell composites were characterized by transmission electron microscopy (TEM) and WAXS techniques. Perspectives of the usage of hollow polyelectrolyte capsules as microreactors for spatially restricted inorganic synthesis were demonstrated. (C) 2002 Elsevier Science B.V. All rights reserved.
