Investigation of Lactones as Innovative Bio-Sourced Phase Change Materials for Latent Heat Storage [PDF]

Molecules, 2019
In the presented work, five bio-based and bio-degradable cyclic esters, i.e. lactones, have been investigated as possible phase change materials for applications in latent heat storage systems. Commercial natural lactones such as ε-caprolactone and γ-valerolactone were easily purchased through chemical suppliers, while 1,2-campholide, oxa-adamantanone ...
