▎ 摘　　要

In this research we studied the influence of sonication time through the properties of polysulfone (PS)-graphene oxide (GO) composites. Nanocomposites of PS-GO 0.5 wt. % were prepared by phase inversion and were exposed to sonication treatment for 30, 60 and 90 minutes. The presence of largely dispersed graphene oxide was evidenced by Transmission electron microscopy (TEM) and Scanning electron microscopy (SEM) and Raman spectroscopy. Fourier transform infrared (FT-IR) investigation indicated no occurrence of interaction between graphene oxide nanosheets and PS. The obtained composites exhibit similar mechanical and thermal properties with those of PS.
