Abstract

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.
