EFFECT OF FUNCTIONALIZED GRAPHENE OXIDE WITH ORGANOPHOSPHORUS OLIGOMER ON FLAME RETARDANT PROPERTIES OF POLYSTYRENE

摘要：

　　A novel organophosphorus oligomer was synthesized to functionalize graphene oxide.Subsequently, the functionalized graphene oxide (FGO) was incorporated into polystyrene (PS) to enhance the integrate properties of the matrix.The microscale combustion calorimeter results showed that introduction of FGO significantly reduced the total heat release (20.8 % reduction) and peak heat release rate (38.2 % reduction) of PS.In addition, the thermogravimetric analysis/infrared spectrometry analysis results indicated that the amount of organic volatiles and toxic carbon monoxide of PS was remarkably reduced.The physical barrier effect of FGO and the synergistic effect between organophosphorus oligomer and FGO were main causations for these properties improvement.
