Figure 3. SWAXS pattern of GO/SBR composite.

The three peaks at 1.5, 3.0, and 4.6 nm⁻¹ indicate a typical high order lamellar structure with a long period of 4.2 nm. The weak and broad peak at 7.8 nm⁻¹ indicates a distance of 0.8 nm. The inset shows the interlayer distance of the sandwich structure of GO/SBR composite. In the schematic representation of “layer-by-layer” sandwich structures consisting of GO sheets and rubber, the GO sheets are presented in blue lattice structure, the rubber between GO sheets are presented in green chains.
