Graphical Abstract

Thumbnail image of graphical abstract

An encapsulation of silver nanoparticles has been developed based on a template technique. Microporous films containing Ag+ ions were constructed by emulsion micelles of PEO-block-PMMA amphiphilic diblock copolymers. Ag+ ions are located around peripheral PEO phases of micropores. Subsequently, Ag nanoparticles (ca. 23 nm in diameter) within the micropore have been prepared by the addition of a chemical reductant, e.g. NaBH4.
