Recently, the preparation of composites based on polyurethane （PU） and carbon nanotube （CNTs） has been paid much attention to. In this paper, the research progress in PU/CNTs composites is summarized. The properties of PU and CNTs as well as the modified treatment methods of CNTs are briefly reviewed. The main preparation methods of PU/CNTs composites, including physical blending and in-situ polymerization, are introduced. The effects of CNTs on the properties of PU/CNTs composites are reviewed in detail. It indicates that the properties such as mechanical property, electrical property, optical property, etc, are improved due to the addition of CNTs. The existing problems and development direction of the future in the research area of PU/CNTs composites are also discussed.
