Abstract
Abstract This paper investigates the effect of three different ring electrode configurations (copper wire electrode [CWE], copper foil electrode [CFE], and copper block electrode [CBE]) on the characteristics of the ring–ring typed atmospheric pressure plasma jet (APPJ) and polyethylene terephthalate modification. The characteristics of APPJ were simulated and experimentally explored. The results show that APPJ with CWE has the maximum electric field magnitude, power, concentration of reactive species, and gas temperature. While CBE has the most uniform electric field distribution and the most stable discharge process. Besides, CWE has the maximum hydrophilization rate while the CBE has the most uniform modification area. The plasma characteristics and modification effect of APPJ with CFE fall in between.
