Fig. 1 — Microscopy images and XPS analysis of CNT powders. Panel a Transmission electron microscope (TEM) images of S-, SF-, L- and LF-CNT. Scale bar: 100 nm. Panel b Optical microscope images of S-, SF-, L- and LF-CNT. Scale bar: 2 μm. Panel c CNT external diameter distribution. Panel d CNT length distribution. Typical spectra of the C1s (Panel e and f) and O1s core level (Panel g and h) obtained for L- (Panel e and g) or LF-CNT (Panel f and h). S-CNT: short-carbon nanotubes; SF-CNT: short functionalized carbon nanotubes; L-CNT: long carbon nanotubes; LF-CNT: long functionalized carbon nanotubes
