The preparation and application of a graphene-based hybrid flame retardant containing a long-chain phosphaphenanthrene

Abstract A novel hybrid flame retardant combining graphene oxide (GO) with long-chain phosphaphenanthrene was fabricated via surface grafting reaction. Taking advantageous of the double barrier effects, including the physical shield contributed by graphene nanoplates during the initial stage and the...
