SEM images of CC. (a) Pristine CC. (b) Exfoliated CC in low magnification. (c) Pristine CC in high magnification. (d) Exfoliated CC at the same magnification.
(a) SEM image of exfoliated CC in high magnification, (b) AFM image of GS exfoliated from CC. (c) TEM image of exfoliated GS. (d) High resolution TEM image of GS.
Schematic of the GS exfoliation on CC. (a) CC was woven by carbon fiber. (b) Carbon fibers were consisted of anisotropic graphite layers and amorphous carbon. (c) After chemical oxidation, the graphite layers outside were terminated by functional groups. (d) After heating, GS were exfoliated from outside graphite layers.
GS deposited on CC by electrophoresis. (a) Low magnification image. (b), (c), and (d) High magnification images.
Field emission of CC. (a) Field emission current density of pristine CC, GS deposited CC. and exfoliated CC. (b) Corresponding F-N plot. (c) Field emission stability of pristine CC. (d) Field emission stability of exfoliated CC.
(a) Schematic for luminance observation, (b) vertical view, (c) side view of luminance.
