Figure 2From: Functionalised graphene sheets as effective high dielectric constant fillers SEM images of CNT/PDMS and FGS/PDMS composites. (Top) SEM images of CNT/PDMS composites: (a) 0.5 wt.%, (b) 1.0 wt.%, and (c) 2.0 wt.%. The inset shows CNT agglomerates present in the sample. (Bottom) SEM images of FGS/PDMS composites: (d) 0.5 wt.%, (e) 1.0 wt.%, and (f) 2.0 wt.%. The scale bar corresponds to 5 μm.Back to article page
