NOVELTY - Preparation of polyphenylene sulfide/graphene quantum dot composite flame retardant comprises dispersing polyphenylene sulfide in dimethyl formamide solution, adding graphene quantum dot and polyvinylpyrrolidone, ultrasonically dispersing for 20-30 minutes, stirring to 60-70 degrees C for 20-24 hours, filtering, washing, and drying. USE - The method is for preparation of polyphenylene sulfide/graphene quantum dot composite flame retardant used for electronic appliances, communication equipment, automobiles and building materials. ADVANTAGE - The composite flame retardant improves flame retardancy of polymer material, and has good flame retardant properties.
