Figure S2 Additional morphology characterizations of CNF/CNC-900 film. (a) A low magnification HiM image showing the uniform porous structures in a large area; (b) the large scale AFM in an area of 20 μm × 20 µm.
Figure S3 (a) The TEM images of CNF/CNC film with ALD coating. The inset shows partially crystalline structure of the Al2O3 layer; (b) shows the corresponding electron diffraction pattern.
Figure S4 The selected area electron diffraction patterns of CNF/CNC-900 film (a) before and (b) after removing ALD Al2O3 layer. The (002) and (101) rings of carbon are overlapped with the (012) and (113) rings of Al2O3.
