The study on it has covered chemical physics, interfacial phenomena, heat and mass transfer and some fundamental fields. This new material will accompany the advancing of future engineering and ...

The PI layers enable the film stacks to achieve regular out-of-plane deformations, critical for efficient heat transfer. When an electric field of 80 MV/m is applied, the polymer films compress ...

When an electric field is applied, the polymer layers compress (electrostriction) and release heat (electrocaloric effect). When the electric field is removed, the layers relax and absorb heat from ...

Highly efficient solid-state heat pumps without compressors – that is the vision of Fraunhofer researchers. With the recent completion of the ElKaWe ...
