NOVELTY - Complex material comprises 3-45 wt.% flame retardant and 55-97 wt.% graphene oxide based on the total amount of the composition. USE - The film is useful for flame retardant material (claimed) and heat alarm devices. ADVANTAGE - The film provides thermal stability; flame retardant property; and has high deformation and tensile strength. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for (1) film comprises 3-45 wt.% flame retardant and 55-97 wt.% graphene oxide based on the total amount of the composition and the average thickness of the flame retardant graphene oxide film is 10-100 mu ; and (2) preparing the film comprising (a) taking graphene oxide and flame retardant in the solvent, to obtain solution A, (b) coating the solution A on the base plate and drying, to obtain the flame retardant graphene oxide.
