摘      要：We present the variations of electrical parameters of dielectric barrier discharge(DBD)when the DBD generator is used for the material modification,whereas the relevant physical mechanism is also *** equivalent circuit model is applied for a DBD generator working in a filament discharging mode,considering the addition of epoxy resin(EP)as the plasma modified *** electrical parameters are calculated through the circuit *** surface conductivity,surface potential decay,trap distributions and surface charge distributions on the EP surface before and after plasma treatments were measured and *** is found that the coverage area of micro-discharge channels on the EP surface is increased with the discharging time under the same applied AC *** results indicate that the plasma modified material could influence the ignition of new filaments in return during the modification ***,the surface conductivity and density of shallow traps with low trap energy of the EP samples increase after the plasma *** surface charge distributions indicate that the improved surface properties accelerate the movement and redistribution of charge carriers on the EP *** variable electrical parameters of discharge are attributed to the redistribution of deposited surface charge on the plasma modified EP sample surface.
