SEM images of (a,d) an as-grown CNT web, (b,e) an as-grown CNT bundles, and (c,f) a CSA-CNT fiber. Insets in (d–f) show the corresponding power spectra. Scale bar in (a–c): 1 μm. Scale bar in (d–f): 500 nm. (g) Angular intensity distributions of the CNT samples, obtained from the power spectra shown in (d–f). Fitting lines with the Lorentzian function and individual fits are depicted by the solid lines and the dotted lines, respectively. (h) Chebyshev orientation parameters of the CNT samples evaluated by the FFT image analysis.
