Organic functionalization of the external walls of DWNTs, followed by controlled thermal treatment under an inert atmosphere, can disclose the inner tubes, which are ready for direct investigation via spectroscopy and microscopy. The latter‐exposed tubes, showing larger diameter compared to the thin inner ones of the pristine DWNTs, are thermally unstable and decompose during annealing.
