| Abstract: |
| Electrocaloric refrigeration technology is a solid-state cooling technique based on the manipulation of electric fields. This technology exploits the temperature variations induced in electrocaloric materials under the influence of an electric field to achieve refrigeration effects. Due to its advantages, such as zero direct carbon emissions and high efficiency, it has garnered widespread attention, particularly in the context of global warming and carbon reduction objectives. Since the discovery of the giant electrocaloric effect in 2006, electrocaloric refrigeration technology has undergone rapid development, notably in the improvement of electrocaloric materials and devices. This article provides an analysis and discussion focused on electrocaloric refrigeration device research, electrocaloric polymer nanocomposite materials, and high-entropy optimization of electrocaloric materials. It commences by introducing the fundamental principles of the electrocaloric effect and current advancements in active regenerative electrocaloric refrigeration devices. Subsequently, it summarizes progress in electrocaloric polymer nanocomposite materials, along with strategies for high-entropy optimization and interface polarization enhancement. Finally, it offers insights into future research directions for electrocaloric refrigeration technology within the fields of working substances and systems. |
