Schematic for the direct growth of CNT onto vertical graphene nanosheets (VGNS) (a). Photograph of the as-grown VGNS/CNTs on a flexible graphite substrate (b). SEM micrograph of pristine VGNS prior to CNT growth (c). SEM micrograph of the final hybrid VGNS/CNTs nanoarchitecture in which the graphene nanosheets were decorated with a high density of CNT (d). Cross-sectional (e) and high-resolution (f) SEM images of the VGNS/CNT (Reproduced with permission of [44]. Copyright Wiley, 2014).
