Micro/nano encapsulated PCM has played an increasingly important role in energy science and other fields.In this paper,preparation of micro/nano encapsulated PCM is reviewed.Preparation methods of micro encapsulated PCM（MEPCM） mainly include interfacial polymerization,in situ polymerization,coacervation suspension polymerization etc.Preparation methods of nano encapsulated PCM（NEPCM） mainly include miniemulsion polymerization and in situ polymerization.Applications of micro/nano encapsulated PCM in modern buildings,such as concrete,wall,wallboard and floor board are described.Present existing problems and the corresponding solutions in the use of micro/nano encapsulated PCM are discussed,such as PCM could not complete full phase change cycles at a high temperature in summer.The future key research directions could be optimizing the synthesis process,strengthening the physicochemical properties of the capsule,and improving its compatibility with inorganic building materials.
