Application of Nanotechnology in Phase Change Heat Storage

Combined with the special size effect of nanoparticles, applying nanotechnology to the preparation and improvement of phase change thermal storage materials, we can obtain nanometer phase change materials such as nanofiuids, nano-encapsulated phase change materials, nano-composite phase change materials and a series of excellent perfomaance ofnano phase change heat storage materials. The new nanoscale phase change materials is gradually being used into the life and production of various areas for heat storage and leads the development direction of phase change thermal storage technology. In the paper, it was a review of research progress of three kinds of nanometer PCMs mentioned above and recommended their application and direction.
