Abstract

Optical emission spectroscopy was used to characterize the gas phase in a gliding arc tornado reactor used for plasma applications. Results concerning the transition between spark and fully developed arc regimes are presented, by comparing with the electrical characteristics of the discharge. An extended analysis of spectra of air and helium discharges mixed with water and hexamethyldisiloxane vapors was performed, with the identification of active radical species involved in the surface functionalization of polymeric nanoparticles.

滑弧龙卷风装置的电气和光学特性的表征

摘要

使用光发射光谱法来表征用于等离子体应用的滑动电弧龙卷风反应器中的气相。通过与放电的电气特性进行比较，给出了有关火花和充分发展的电弧状态之间过渡的结果。进行了与水和六甲基二硅氧烷蒸气混合的空气和氦气放电光谱的扩展分析，并确定了参与聚合物纳米粒子表面功能化的活性自由基种类。
