On the basis of a thin‐wire contact electrode structure, a nonuniform electric field is designed to realize diffuse discharge in atmospheric air. A new method of high‐efficiency treatment of carbon fiber fabrics by glow discharge plasmas at low discharge voltage is proposed. Through this method, carbon fiber fabrics are directly used as electrodes, the plasmas are directly formed on the surface, and a strong electric field region can be formed on the surface of carbon fiber fabrics. The high‐active plasmas generated in this study can not only introduce nitrogen functional groups that are difficult to be introduced by traditional air plasma treatment methods and a large number of oxygen functional groups on the surface of carbon fiber fabrics but also improve the surface roughness and wettability of the material. In addition, the important effects of surface electric field intensity and plasma treatment time on the modification effect were investigated. It lays a good technical foundation for the industrial application of carbon fiber surface modification with high efficiency and continuity in atmospheric air.

碳纤维织物的大气辉光放电等离子体产生及表面改性研究

在细线接触电极结构的基础上，设计了非均匀电场以实现大气中的扩散放电。提出了一种在低放电电压下通过辉光放电等离子体对碳纤维织物进行高效处理的新方法。通过这种方法，碳纤维织物直接用作电极，等离子体直接形成在表面上，并且可以在碳纤维织物的表面上形成强电场区域。本研究中产生的高活性等离子体不仅可以引入传统空气等离子体处理方法难以引入的氮官能团，而且可以在碳纤维织物表面引入大量的氧官能团，还可以改善表面粗糙度和材料的润湿性。此外，研究了表面电场强度和等离子体处理时间对改性效果的重要影响。为在大气中高效连续地进行碳纤维表面改性的工业应用奠定了良好的技术基础。
