Abstract: A graphene has drawn much concern due to its excellent impermeability to ga-ses, adsorption capacity, mechanical strength and thermal stability. The graphene's dispensa-tion and compatibility has been obviously improved via modification, allowing the graphene to be used in fire-resistant coatings. The fire-resistant mechanism of graphene has been investi-gated deeply. Specially the synergy of graphene with other flame retardants can greatly improve fire-resistant performance of coatings. The biodegradability of the graphene in natural environ-ment indicates that the graphene is the most promising component in coatings. This article presents current progress and discusses the major challenges and prospects of the graphene in the fire-resistant coatings.
