As a non-contact, real-time, accurate, and flexible control technique, the magnetic field has been widely utilized in a variety of applications, including industrial grab, robot drives, medical assistance, etc. However, non-magnetic phase change materials (PCMs) are difficult to manipulate with magnetic fields. Recently in Nature Communications, He et al. innovatively proposed magnetically tightened form-stable PCMs with the integrated multi-functions of being leakage-proof, having highly thermal/electrical conductivities, robust mechanical strength, dynamic assembly, and shape reconfiguration by introducing hard magnetic particles. Additionally, they developed free-standing temperature control and high-performance thermoelectric conversion systems based on magnetically tightened form-stable PCMs.

磁场作为一种非接触、实时、准确、灵活的控制技术，已广泛应用于工业抓取、机器人驱动、医疗救助等多种应用中。然而，非磁性相变材料（PCM）很难用磁场进行操作。最近在Nature Communications上，He 等人。创新性地提出了具有防漏电、高导热/导电性、强大的机械强度、动态组装和通过引入硬磁颗粒的形状重构等集成多功能的磁力紧固形状稳定的相变材料。此外，他们还开发了基于磁性紧固形状稳定 PCM 的独立式温度控制和高性能热电转换系统。
