Abstract
Energy of propagating brush discharge（ PBD） was investigated by the relationship between surface potential of a film before and after PBD and total charge transfer during approaching a grounded needle electrode parallel to it. As for the result, the slope of curve, energy divided by charge transfer, is different from polarity. It is indicated the number of branches affects the difference of surface potential before and after PBD despite the same charge transfer.
