Recently, the dielectric barrier discharge (DBD) plasma at atmospheric pressure has become higher and higher with its ever increasing applications to surface modification of materials. The relationships among those electricity parameters, such as discharge current and discharge power which is measured by Lissajous figure of the oscilloscope, are analyzed by using improved dielectric barrier discharge equipment. The experimental results indicate that discharge gap, working gas and the rate of flow all have influence on these electricity parameters. The 1.0～2.5mm discharge gap is optimum for surface modification of materials. The result is of great importance to dielectric barrier discharge at atmospheric pressure and its application to surface modification of textile materials.
