Precise control of the electro chemical charging enabled us to follow the detailed development of the tangential displacement (TG) mode of SWCNT bundles in dependence on the electrode potential. The response of the TG mode to electrode potential was dependent on electrolyte used as a consequence of different doping efficiency.We demonstrate that the liquid electrolyte solution (LiClO4/CH3CN) has superior doping efficiency to those of both the tested polymer electrolytes.
