▎ 摘　　要

NOVELTY - Preparing polyphenylenesulfide composite material grafted with graphene oxide involves using anhydrous sodium sulfide, dichlorobenzene and dichloroaniline as raw material, N-methyl pyrrolidone as solvent, using isopropyl titanate as catalyst, using nitrogen as protective gas, reacting for 1.5 ~ 2.5 hr at 260 ~ 280 degrees centigrade in alkaline environment, washing the sample, filtering, drying to obtain amination polyphenylthioether and (ii) ultrasonically dispersing the graphene oxide in tetrahydrofuran solution, adding aminated polyphenylenesulfide, stirring and reacting for 10 ~ 12h at 45 ~ 55 degrees centigrade to obtain polyphenylenesulfide-graphene oxide, adding hydrazine hydrate, reacting for 1.5 ~ 2.5 h at 75 ~ 85 degrees centigrade washing and drying to obtain polyphenylenesulfide.
