Phase Change Materials (PCM) store and release thermal energy through solid-liquid transitions at near-constant temperature, exploiting latent heat capacities orders of magnitude greater than sensible heat storage. Research spans material classes — paraffins, salt hydrates, fatty acids, eutectic mixtures — alongside critical challenges in thermal conductivity enhancement, supercooling mitigation, long-term cycling stability, and containment through micro- or macroencapsulation.
Die Systemintegration umfasst die Geometrie von Wärmetauschern, PCM-Suspensionen und Nanokomposit-Matrizen. Die Anwendungsbereiche reichen von der thermischen Gebäuderegulierung und Kühlkettenlogistik bis hin zur Energiespeicherung im Netzmaßstab und der thermischen Steuerung von Raumfahrzeugen.
