MICROGELS AND CORE-SHELL PARTICLES

摘要

An overview of the synthesis and applications of microgels and core-shell particles is provided, with emphasis on work originating from the author's laboratory. Microgels, which are cross-linked polymer latex particles, can be used for selective uptake of ions or polymers, or the controlled release of various compounds. Various methods for the synthesis of core-shell particles are described such as interfacial polymerization, layer-by-layer deposition, "colloidosomes", internal phase separation, and silica shells. The release kinetics for controlled (sustained or triggered) release purposes is discussed.
