Abstract: Graphene oxide/polyimide nanocomposites were synthesized by in situ polymerization using 4,4’-oxydianilline, graphene oxide and pyromellitic dianhydride. A homogeneous disperson of graphene oxide was achieved in polyimide matrix as evidenced by scanning electron microscopy while the structure of the polymide and graphene oxide is stable in the preparation process by Fourier transform infrared spectroscopy and X-ray diffraction. The resultant polyimide/graphene oxide nanocomposites not only exhibite excellent thermal resistance by differential scanning calorimetry ,but also have stronger thermal stability than pure polyimide by thermogravimeticanalysis due to the strong interfacial interaction between the graphene oxide and polyimide matrix, which is favorable for practical use in heat-resisting material.
