Abstract

A novel way of preparing carbon nanotubes modified glassy carbon electrodes is introduced

and their electrochemical properties are tested and analyzed.With the help of polyimide

carbon nanotubes are dispersed homogeneously and cut short by mechanical ball milling.After etching process

ends and edges of many carbon nanotubes are exposed on the surface of the film and became the active sites of electrochemical reactions.The composite film of carbon nanotubes and polyimide

which is the interface of the carbon nanotubes modified glassy carbon electrode

is controllable

homogeneous and stable by the images from scanning electron microscope.The electrochemical performance of the carbon nanotubes modified electrode is tested by cyclic votammetry method.The results show that this type of electrodes are sensitive to trace substances and also have the function of electrocatalysis.
