Phase change materials for automotive applications

The study also addresses the challenge of solidifying supercooled sugar alcohols by enhancing their crystallisation using acetamide eutectic mixtures. COSMOtherm is used to model eutectic points using cyclohexyl diesters and terephthalate diesters, demonstrating highly accurate predictions with deviations of less than 3.2 K for eutectic temperatures. The in-house synthesised novel saturated cyclic diester, didodecyl cyclohexane dicarboxylate (CH12), emerged as the best candidate, showing superior performance in specific heat capacity, electrical resistivity, thermal stability, and durability compared to commercial PCM products, demonstrating its potential for BTMS applications in EVs.<br><br><i>Thesis is embargoed until 31 July 2035.</i>
