等离子体表面改性是一种在不改变本体性能的情况下改善聚合物表面性能的有利技术。然而，对于颗粒来说，存在颗粒混合和与等离子体接触不充分、处理时间难以控制等问题。在这项研究中，开发了一种与滑动电弧放电产生的等离子体相结合的旋风反应器。旋风反应器有望提供颗粒和等离子体之间的有效接触以及在旋转颗粒区域的尺寸选择性处理。
Surface modification with plasma is a favorable technique to improve surface properties of polymer substance without changing bulk properties. For the particles, however, there are some problems such as insufficient mixing of particles and contact with plasma, and difficulty in controlling the treatment time. In this study, a cyclone reactor combined with plasma generated by gliding arc discharge was developed. The cyclone reactor was expected to provide efficient contact between particles and plasma as well as size-selective treatment at the swirling particles region.
