| 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 ... |
