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.

基于多电势和芳纶织物表面改性的大气辉光放电等离子体生成研究

提出了一种基于多电位复合网络-表面叠层电极结构的，在大气中具有良好扩散性的大面积辉光放电等离子体形成方法。该方法可以增强空间电场强度，并在电压低于1 kV的条件下产生辉光放电等离子体。通过交变电场，带电粒子从电极表面扩散到空间，以增强对芳纶织物的处理。根据芳纶织物的表面形态，接触角和表面能的变化，可以看出，经等离子体处理的材料的表面粗糙度和表面能得到了显着改善。处理30 s后，接触角减小83.85°，表面能增加3.4倍。该方法具有放电电压低，放电均匀性好，材料处理效果好等优点。对于芳纶织物表面改性的高效工业化具有良好的应用前景。
