Synthesis and statistical study of multi wall carbon nanotubes on Cu substrate using electrochemical cell

Abstract EN

Multi wall carbon nanotubes (MWCNTs) were grown directly on copper substrate and in the acetonitrile / de-ionized water (1 % v / v) electrolyte of the electrochemical cell using different growth temperatures.

The effects of substrate temperature and growth time over the MWCNTs structure were investigated.

MWCNTs were characterized by Scanning Electron Microscopy (SEM), Low Magnification Transmission Electron Microscopy (LMTEM) and Atomic Force Microscopy (AFM).

TEM characterization indicate a transition from non-growth at 288 K to negligible growth at 308K then to excellent growth at 338K, AFM characterization indicate a Gaussian distribution growth on Cu substrate with maximum percentage to 110 nm diameter.
