Figure 3: Characterization of the as-obtained ACT/graphene composite.
From: Cotton-textile-enabled flexible self-sustaining power packs via roll-to-roll fabrication
(a) SEM image of ACT (scale bar, 250 μm), inset is the amplified SEM image (scale bar, 5 μm). (b) SEM image of graphene oxide, inset is the atomic force microscopy image of graphene oxide nanosheets (with a height profile showing a step of 1.1 nm marked by the red arrows). (c,d) SEM images of ACT/graphene composite at different magnifications (scale bars, 10 μm for c and 2 μm for d), insets of d are the HRTEM image (scale bar, 5 nm) and corresponding SAED pattern of graphene nanosheets. (e) Schematic illustration of the ACT fibre with graphene coating, inset is the TEM image of ACT fibre (scale bar, 25 nm). (f) XRD patterns of pure cotton textile, ACT, ACT/graphene oxide and ACT/graphene composite.
