Abstract

PEG4000-based polymer nanocomposites filled with a series of PEG functionalized graphene (GO-PEG) have been prepared by solvent blending. The structure and properties of these nanocomposites could be studied by Fourier transform infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TG) in detail. The results indicate that functionalized graphene is dispersed on a molecular scale and the corresponding composites show the layer-aligned structures. The thermal stability of polymer nanocomposites could be improved significantly by the strong interfacial interactions between both components mainly. At last, the schematic illustration of the synthesis of layer-aligned polymer nanocomposites has been provided.
