Microencapsulation of PCMs typically involves a single purpose: thermal energy storage. What if you could make that material glow
as well? That's what three researchers at the Beijing University of Chemical Technology
set out to find. They designed and synthesized PCM microcapsules with an n-eicosane
core and zirconium dioxide
shell to attain the characteristics of latent-heat storage/release and photoluminescence
. Potential applications include intelligent fibers and photosensitive devices.
