The low temperature streamer at atmospheric pressure has good characteristics of pollutant removal, and the characteristics of the streamer are closely related to the discharge conditions, and the structure and material of the electrode also affect the characteristics of the streamer. In our work, the argon gas was discharged under different conditions and the morphology of streamer was shoot by a high-speed camera, then the morphology of the streamer that generated by the carbon nanotube electrode was compared under the same conditions. The experimental results show that when the electrode is electroplated with carbon nanotubes, the light intensity and the diameter of the streamer will increase, and the morphology of the streamer that in the atmosphere will change regularly with the discharge conditions. The experiment proved that the morphology of the streamer will be influenced by the discharge conditions because of the electric and flow fields, and the carbon nanotube electrode will generate more intense streamer.
