AFM images of pLT and pLT/SWCNT complexes. (a) AFM image of pLT and the height distribution along line A-B. PLT folded to form sphere-like structures on the surface of an Si substrate. (b) AFM image of pLT/SWCNT complexes and the height distribution along line C-D. (c) AFM image of a pLT/SWCNT complex and the height distribution along line E-F. The thicknesses of pLT adsorbed onto the SWCNT varied cyclically in the axial direction of the SWCNT.
