Thermal behavior of polyelectrolyte multilayer microcapsules: 2. Insight into molecular mechanisms for the PDADMAC/PSS system
Article Abstract:
Polyelectrolyte multilayer capsules consisting of poly(diallyldimethylammonium chloride) (PDADMAC) and poly(styrene sulfonate) (PSS) are used as a model system to evaluate the temperature-dependent behavior of polyelectrolyte multilayer films in aqueous media. The thermal history has an influence on the temperature behavior of capsules, especially on those ones terminated with PDADMAC and also the molecular weight of the polyelectrolytes affects the rearrangement of capsules.

Synthesis of nanosized magnetic ferrite particles inside hollow polyelectrolyte capsules
Article Abstract:
Complex inorganic oxides (CoFe2O4, ZnFe2O4, MnFe2O4, Fe3O4) are demonstrated possessing magnetic properties without additional annealing could be synthesized inside hollow polyelectrolyte capsules of 10(mu)m diameter. Ferrites and magnetite are formed gradually in the radial direction from the inner side of the capsule wall to the capsule center, depending on the initial concentration of inorganic salts.

Balance of hydrophobic and electrostatic forces in the pH response of weak polyelectrolyte capsules
Article Abstract:
The role of solution pH and ionic strength on the swelling behavior of capsules composed of the weak polyelectrolytes poly(4-vinylpyridine) (P4VP) and poly(methacrylic acid) (PMA) with different numbers of layers are studied. The stability of the capsules as well as the swelling degree at a given pH could be tuned, when the ionic strength of the medium was altered.
