(a) Drawing of an (8, 6) CNT wrapped by a monolayer of PFO. The backbone polymer atoms are colored. The chemical structure of PFO is shown in (c). (b) An AFM image of a single CNT. The bright spots indicate the existence of aggregate polymer crystals. The inset shows the height profile of nanocrystals and nanotubes, with an 8 nm discontinuity measured.
