Abstract: This paper introduced the applications of nano flame retardants in composites, especially in resinmatrix composites and analyzed the types and characteristics of nano flame retardants with high efficiency, low smoke, low toxicity and good physical properties. The paper also reviewed the current status of layered silicates, carbon nanotubes, polyhedral oligomeric silsesquioxanes and graphene nanosheets at home and abroad. Moreover, the future research directions in this issue were prospected.
