Large-area open air plasma sources for roll-to-roll manufacture High-power density surface plasma generated by diffuse coplanar surface barrier discharge

The aim of the current paper is to introduce technology for the generation of high-power density surface plasma by a diffuse coplanar surface barrier discharge (DCSBD) plasma unit. The diffuse and uniform plasma generated in low-cost gases such as open air enables easy integration into novel or existing roll-to-roll (R2R) lines. We briefly discuss the history of the development of dielectric barrier discharges (DBDs) toward the most advanced plasma sources based on the coplanar arrangement of electrodes. Moreover, we present and discuss the advantages and disadvantages of the effect of volume and coplanar DBD treatments performed in R2R mode on the surface of polyamide.The paper also discusses the potential of R2R plasma treatments for next-generation applications of novel flexible and printed electronics.

Automated summary

This paper introduces the technology of generating high-power density surface plasma using DCSBD plasma unit and discusses its integration in R2R production lines and its effects on the surface of polyamide.
