摘要：

Full of air: Electrostatic layer-by-layer assembly of polyelectrolyte multilayers was successfully accomplished on the surface of an air microbubble (core). The resulting polyelectrolyte shell stabilizes the air microbubbles against collapse and prevents the dissolution of air in aqueous media. Air-containing polyallylamine/ poly(styrene sulfonate)(PAH/PSS) microcapsules have a broad size distribution (1-20 μm). (Figure Presented) © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
