From concept to application. A new phase change material for thermal protection at -11 °C

In this paper we present an example of the application of molecular alloys for thermal protection of biomedical products during transport or storage. Particularly, thermal protection of blood elements have been considered at different temperatures. All steps from basic research to marketing have been addressed. The high latent heat of fusion of the components allows us to propose molecular alloys as materials for thermal energy storage and also for thermal protection over a large range of temperatures, which can be used in many industrial sectors.

“…The research topics of this group have both fundamental and applied purposes and concerns the investigation of the polymorphism and solid-state miscibility of coherent families of compounds and also the application of molecular alloys as tuneable phase change materials (MAPCM) for thermal protection or energy storage. In the past 10 years, numerous works have been undertaken on alkanes (C n H 2n+2 ) [1,2] and alkanols (C n H 2n+2 O) [3,4] which demonstrated in particular the feasibility of molecular alloys of alkanes for the applications [5][6][7]. Our interest is focused here on fatty acids (C n H 2n O 2 ), which are alkanes derivatives and are also promising candidates for the applications.…”

Highlights: C12H26-C13H28 system has a congruent minimum-melting solid solution and polymorphs  The minimum-freezing 17.7 mol% C13H28 blend (at -16 to -12 °C ) is a potential PCM  17.7 mol% C13H28 blend freezes with an enthalpy of 165 kJ kg -1 and no supercooling  The system has a minimum-melting trend, but has no eutectic as literature proposed  Extensive physicochemical studies needed to explain melting/freezing discrepancies AbstractIntegrating thermal storage with phase change materials (PCMs) in refrigeration and air conditioning processes enables energy performance improvements. Herein, the experimental phase diagram of the alkanes system dodecane-tridecane (C 12 H 26 -C 13 H 28 ) is evaluated to find PCMs for freezing applications. For that, the Temperature-history method was coupled with a Tammann plot analysis. The obtained C 12 H 26 -C 13 H 28 phase diagram indicated a congruent minimum-melting solid solution and polymorphs. The minimum-melting liquidus and the polymorphs identified here, agree with previous literature. However, the system does not represent a eutectic, as previously was proposed. The minimum-melting composition is here identified within 15-20 mol% C 13 H 28 compositions. The 17.7 mol% C 13 H 28 is the narrowest minimum-melting composition among those analyzed, melting and freezing between -16 to -12 °C and -17 to -15 °C, with: the enthalpies 185 kJ kg -1 and 165 kJ kg -1 ; no supercooling; and only minor hysteresis. Hence, this blend has potential as a PCM in freezing refrigeration applications.
