用于加热和冷却的电活性聚合物Electroactive polymers for heating and cooling
➀ 弗劳恩霍夫IAP开发了厚度仅4微米的电热聚合物薄膜，用于无制冷剂的热泵系统，可应用于汽车内饰、电子元件和激光设备等领域；
➁ 该材料通过电场调控实现快速温变，电压变化时聚合物极性结构有序排列释放/吸收能量，形成可循环的加热与冷却效应；
➂ 采用多层薄膜堆叠技术和材料改性工艺，提升介电强度和热稳定性，其环保特性有望取代传统压缩机制冷系统。
➀ Fraunhofer IAP develops ultrathin electrocaloric polymer films (4 micrometers) for refrigerant-free heating/cooling systems, targeting applications in vehicles, electronics, and laser systems;
➁ These polymers use electric fields to generate rapid temperature changes, enabling energy-efficient heat pump designs with alternating warm/cold zones;
➂ Multilayer stacking and material optimization enhance performance, offering eco-friendly alternatives to compressor-based refrigeration in the ElKaWe flagship project.
