摘要

本文提出了一种基于同轴传输线谐振器(CTLR)的紧凑型便携式微波大气压等离子体射流(MW-APPJ)发生器。根据电磁模拟,喷射发生器被设计成锥形内导体结构,以确保在低功率下产生等离子体。由于 CTLR 结构的高效率,还实现了混合反应气体的等离子体。利用光学发射光谱测定了等离子体的内在参数和活性物种。此外,还利用 MW-APPJ 设备对聚四氟乙烯表面进行了改性,并在无热损伤的情况下提高了亲水性。

Study of a full coaxial atmospheric pressure plasma jet device and its application to the modification of polytetrafluoroethylene
In this article, a compact and portable microwave atmospheric pressure plasma jet (MW‐APPJ) generator based on a coaxial transmission line resonator (CTLR) was proposed. Based on the electromagnetic simulations, the jet generator was designed as a tapered inner conductor structure that ensures plasma generation at low power. A self‐igniting argon (Ar) plasma jet of 10 mm length was generated at an input power of ~20 W and maintained at 2 W. Thanks to the high efficiency of the CTLR structure, plasmas of mixed reactive gases were also realized. Intrinsic plasma parameters and active species were determined using optical emission spectroscopy. Furthermore, the MW‐APPJ device was used to modify the polytetrafluoroethylene surface, and improvement of hydrophilicity was achieved without thermal damage.
