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 investigated 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 environment 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.
