Title

Understanding orientational dynamics in barocaloric plastic crystal mixes using quasielastic and inelastic neutron scattering

Abstract

Plastic crystals are amongst some of the most promising phase change materials for use in solid-state energy storage and heating/cooling technologies. This is primarily due to a substantial latent heat accompanying their first-order solid-solid phase transitions involving freezing of molecular reorientations. One of the most notable of these materials is neopentylglycol (NPG), where recent experiments on this material have demonstrated colossal barocaloric effects (BCE) that rival longstanding commercial refrigerants for the first time. However, notable drawbacks associated with NPG include low thermal conductivity and significant supercooling effects, where the latter results in undesirable hysteresis during phase transitions. We have recently discovered reduction of hysteresis in binary and tertiary solid solutions of NPG with other related plastic crystals. Here we wish to use quasielastic (QENS) and inelastic neutron scattering (INS) to explore the molecular reorientations in these solid solutions and better understand the underlying cause of the reduced hysteresis.
