摘要： 为了提高等离子体对聚合物材料表面处理的应用效果,提出了一种同轴式带孔内电极介质阻挡放电反应器.实验结果表明:带孔内电极结构具有更高的放电功率,可在更短的时间内使接触角降的更低.该反应器产生等离子体对聚丙烯和聚酯表面改性,其表面接触角分别从90°降低到40°和从88°降低到30°.采用3种工作气体(氦气、氩气和空气),等离子体处理效果依次提高.该研究在工业应用中有着实用价值,为改善聚合物材料表面亲水性提供参考.

Abstract: In order to improve the application effect of plasma on the surface treatment of polymer materials, a coaxial perforated inner electrode dielectric barrier discharge reactor is proposed in this paper, and the experimental results show that the structure of the perforated inner electrode has higher discharge power, which can make the contact angle drop lower in a shorter period of time. The reactor generates plasma for surface modification of polypropylene and polyester, and the surface contact angle is reduced from 90° to 40° and from 88° to 30°, respectively. The effectiveness of the plasma treatment is increased by employing three working gases: helium, argon and air. This study has practical value in industrial applications and provides a reference for improving the surface hydrophilicity of polymer materials.

Key words: dielectric barrier discharge, perforated inner electrode, surface modification, hydrophilicity
