Polyimide(PI) is an importatant substance for more than 40 years due to its mechanical properties, heat, electrical properties, And GO have recently attracted much interests regarding graphene-based (Graphene oxide) hybrid materials. we have synthesized NH2-GO with pyromellitic dianhydride and 4,4’-oxydi-aniline, N,N-dimethylacetamide. In this study, we have prepared amine modified graphene(GO-NH2) through the reduction and functionalization of GO with primary amine.The nanocomposites with polyimide and GO were fabricated with the reaction of GO-NH2, pyromellitic dianhydride, and 4,4’-oxydi-aniline in DMAc solution. Polyimide was chemically attached to the surface of GO.The obtained nanocomposites with polyimide and GO were characterized by SEM,EDX,TGA,DSC,and FT-IR. |
