Figure 2. Investigation of the SWCNT film morphology.

Figure 2

Scanning electron micrographs of a SWCNT film at different magnifications 10,000× (a,b), 50,000× (c), and 200,000× (d). (b), In the image taken at grazing angle (≈ 90° respect with the sample plane normal), it is possible to observe that micro-structures consist of self-assembly ripples made of surfactant and SWCNTs, as evident in (c). (d), Pores in the SWCNT network (marked with red arrows). (e), Micro-structure height as a function of film thickness. (f), Three-dimensional sketch of a pore in the SWCNT network.
