Dry-Transfer of Aligned Multiwalled Carbon Nanotubes for Flexible Transparent Thin Films

Figure 1

(a) Side profile SEM micrograph of the source MWCNTs. Inset: high-resolution SEM micrograph of the lower highlighted area demonstrating the extremely linear growth. (b) Areal SEM micrograph of the upper highlighted area in (a) illustrating the spaghetti-like morphology of the forest surface. Inset: HR-TEM micrograph showing four graphitic side walls. (c) Raman spectra (3 mW, 633 nm) of the as-grown MWCNTs. No distinguishable RBM peaks were observed (100-500 cm⁻¹ wave numbers not shown), relative to the spectrometers noise floor, suggesting a largely multiwall population.
