摘　　要：水合盐相变材料作为潜热储存技术的储能物质在建筑、电池、微电子、热疗等热管理领域展现出良好的应用前景。通过原子力显微镜(AFM)技术可以实现水合盐相变材料表面的纳米尺度形貌表征和纳米力学成像,有助于在纳米尺度上原位跟踪和揭示材料表面发生的热物理性能演变,从根源上提升材料的循环稳定性。文章回顾了AFM在水合盐相变材料研究中的一些应用。作为AFM表征的前提与基础,首先,介绍了水合盐相变材料的精确制备。其次,讨论了AFM形貌表征和定量纳米力学成像在水合盐表面演化、共晶点确认、纳米尺度相分离、聚合物复合等方面的应用。最后,展望了未来的主要发展方向和趋势。As energy storage materials for latent heat storage technology,hydrated salt phase change mate-rials(PCM)have shown broad application prospects in the fields of thermal management in buildings,bat-teries,microelectronics,hyperthermia and so on.Atomic force microscopy(AFM)has provided a power-ful technology for nanoscale topographical,nanomechanical,and other performance imaging on the sur-faces of hydrated-salt PCM.This is helpful to track and reveal the thermophysical properties evolution on the surface in situ at the nanoscale,and improve cyclic stability of the materials from the root.This paper re-views some applications of AFM in the study of hydrated-salt PCM.As the premise and basis of AFM char-acterization,the accurate preparation of hydrated salt phase change materials is first introduced.The appli-cations of AFM morphology characterization and quantitative nanomechanical imaging in hydrate salt sur-face evolution,eutectic point confirmation,nanoscale phase separation,and polymer recombination are discussed.The main development trends and directions for the future are prospective.
