Abstract: The paper reviewed the recent research progress in nano thermal insulation coatings and summaried up the characteristics and the current research status of three types of thermal insulation coatings, including the nano thermal barrier coating, nano semiconductor thermal insulation coatings and nanopore thermal insulation coating. The emphasis was focused on the role of the nano-materials to reduce the thermal conductivity of the coating as well as some new nanomaterials in the development of the coatings. The problems and difficulties of the preparation of the thermal insulation coatings were discussed.
