A single-step synthesis of inorganic microcapsulesfilled with organic liquids or polymers is achieved by complexation of cationic surfactant–stabilized miniemulsion latexes with disc-shaped silica particles. Interlinking the discs by condensation with silicic acid further stabilizes the capsules. The structure survives depolymerization and evaporation of a polymeric organic template. The Figure shows hollow nanocapsules.
