A method of forming large‐area glow discharge plasmas with good diffusivity in atmospheric air based on the composite network‐surface laminated electrode structure with multiple potentials is proposed. This method can enhance the intensity of the space electric field and generate glow discharge plasma under the condition that the voltage is lower than 1 kV. Through the alternating electric field, the charged particles diffuse from the surface of the electrode to the space to enhance the treatment of aramid fabric. According to the changes of surface morphology, contact angle and surface energy of aramid fabric, it can be seen that the surface roughness and surface energy of the material treated by plasma are significantly improved. After 30 s of treatment, the contact angle decreases by 83.85° and the surface energy increases 3.4 times. This method has the advantages of low discharge voltage, good discharge uniformity, good material treatment effect, and so forth. It has good application prospects for the industrialization of aramid fabric surface modification with high efficiency.
