Solid-state cooling technologies, such as electrocaloric heat pumps, offer a sustainable alternative to traditional refrigeration methods by eliminating the need for harmful refrigerants. However, the performance of these technologies is strongly influenced by the thermal exchange at the interface between the electrocaloric material and the heat transfer medium. Using bipolar pulsed magnetron sputtering, this doctoral thesis addresses this challenge by developing long-lasting superhydrophilic coatings and surface modifications that enhance latent heat transfer through improved wettability.


Brief CV

Maria works at the Fraunhofer Institute FEP in Dresden at her PhD project within the Fraunhofer consortium ElKaWe (Electrocaloric heat pumps). She is interested in developing coatings with an electrical insulating effect and hydrophilic surface for use in electrocaloric heat pumps under the day to day supervision of Dr. Fred Fietzke.
