Abstract

Several methods used for the synthesis of carbon nanotubes have been developed in the last decade. The preparation techniques used, and their associated parameters, have an ultimate effect on the structure of the resulting nanotubes. Consequently, it is of great interest to compare the structure of carbon nanotubes synthesized by different techniques. We investigated a range of nanotubes of different origin by scanning probe microscopy (TM-AFM), and by scanning electron microscopy and energy dispersive spectroscopy (SEM-EDS). Three different types of nanotubes have been investigated: commercial SWNT and MWNT, MWNT (synthesized using a CCVD process) and its SiO2 coated variant, and nanostructures produced using an electrochemical method. A preparative technique is described and different tube parameters are measured. The quality of coated MWNT-s is investigated and nano-structured rings are revealed in samples obtained by electrolysis of molten salts on graphite electrodes.
