Fire warning and fire retardant coatings could realize the dual role of active early warning response and passive fire retardant protection. Compared with the traditional fire detection alarm that needed to be installed in a specific location, the contact area between the coating sensing materials and the flame was greatly increased, which had important application value in improving the early warning efficiency and the fire safety performance of combustible materials. Based on the thermal response characteristics of sensing materials, this paper discussed the fire warning mechanisms of resistance-based and voltage-based coatings, and explained three fire retardant mechanisms of coatings. The research and application status of various coatings based on sensing materials such as graphene oxide, carbon nanotubes, metal oxides, and MXene in fire warning and fire retardant performance in recent years had been reviewed. It was pointed out that fire warning and fire retardant coatings had relatively single performance, and it was necessary to endow them with hydrophobic, oleophobic, and self-healing properties to achieve multi-functional coatings. The preparation technology of large-size coating needed to develop to achieve market production, combined with artificial intelligence technology to achieve a higher level of early warning fire retardant applications, and its future development trend was prospected.
