Microscale polymer bottles corked with a phase-change material for temperature-controlled release

Angew Chem Int Ed Engl. 2013 Sep 27;52(40):10468-71. doi: 10.1002/anie.201305006. Epub 2013 Aug 20.

Abstract

Keep your wine chilled! Microscale polystyrene (PS) bottles are loaded with dye molecules and then corked with a phase-change material (PCM). When the temperature is raised beyond its melting point, the PCM quickly melts and triggers an instant release of the encapsulated dye. The release profiles can be manipulated by using a binary mixture of PCMs with different melting points.

Keywords: hollow particles; phase-change material; temperature-controlled release.
