Abstract:
Microcapsules are desired vehicles for controlled delivery of active components as drugs and other functional materials. Emulsion droplets are ideal templates for the encapsulation of different kind of active components as spherical microcapsules. The size and size distribution of the droplets determine that of the microcapsules. Membrane emulsification produces droplets in a drop-by-drop manner and therefore provides a precision production route for emulsions and microcapsules. This talk reviews our recent research in the development of membrane technologies and their use in varied emulsion systems for precision control of size and size distribution. The design of emulsion systems using surfactants and nanoparticles as emulsifier is included for the production of matrix and core-shell microcapsules for responsive or triggered release.
