The nano-encapsulated phase change materials （NEPCMs） are a kind of novel composite phase change materials. The nano-capsule of phase change materials including the structure composition, principles, and some functions, such as the kind of the capsule-wall and the capsule-core, and/or the principle to select the suitable materials was introduced. And the compare of the nanoeapsule with microcapsule was given. The progress of the NEPCMs including the preparation methods, such as mini-emulsion polymerization, in-situ polymerization and interface polymerization was focused on. Finally, the applications of NEPCMs in building energy-saving, functionally thermal fluids, costume, aerospace and military were summarized.
