Abstract
The use of atmospheric pressure non-thermal plasmas in diverse applications has
resulted in development of a wide variety of plasma sources. While corona discharges
have been studied for more than a century to understand the fundamentals of electrical
gas discharges, the use of the corona discharge in materials processing has been
often very limited. In this work, we investigated an atmospheric pressure weakly ionized
plasma source based on the corona discharge; and utilized the developed plasma
source for materials processing. The plasma was generated with a distinctive pointto-
point electrode geometry that achieved enhanced plasma generation including back
corona. We investigated early growth of plasma polymerized acetylene deposition
and demonstrated that this deposited material could modify the surface properties of
natural fibers with a reasonable processing time. We showed the viability of the developed
plasma source to generate etching plasmas that included admixtures of dry air
and oxygen. This work demonstrated the potential for corona based plasma sources to
provide cost-effective and scalable operation compared to other commercially available
atmospheric pressure plasma sources.
