摘要：
Various methods for preparing hybrid nanostructures from aqueous polymer dispersions were studied. Styrene or acrylate homo- and co-polymer core latex particles need to be modified with a reactive comonomer. Accurate control over pH and process conditions is required to avoid latex coagulation or, in case of organic particles with uniform composition, incipient intraparticle crosslinking. It is observed that these nanostructures can be useful precursors of hollow spheres with well-defined size and composition.
