Atmospheric pressure plasmas (APPs) have been actively studied since the 1990s[1]. APPs can be discharged in open spaces (1 atm). The classification of APPs is based on their discharge structures and discharge modes, which include dielectric barrier discharge (DBD), corona jet, glow discharge, arc torch, micro-hollow cathode discharge (MHCD), and inductively coupled plasma (ICP)[1]. Plasma with the desired physical and chemical characteristics is generated by adjusting factors such as the input frequency, input voltage, input current, input waveform, and supply gas. Because of its various favorable characteristics, the application of APP to various fields, such as the biomedical, material, and energy/environmental industries, has been considered, and basic research on APPs has been actively conducted worldwide[1]. In many cases, the plasma system is designed using non-flexible electrodes for generating the plasma, which restricts the volume and design of the overall system. Currently, flexible devices such as displays, solar cells, energy storage, and sensors are important research areas[1]. Recently, there is a significant interest in flexible APP for applications to remove volatile organic compounds(VOC). For the practical application of APP electrode to decomposition of VOC, the surface properties of the electrode should be improved in order to overcome the electrical short circuit problem in very wet environmental condition. In this study, we present a flexible APP wire electrode coated with thermally stable polymer in order to improve the weather resistance of the electrode. The detail on the surface properties will be presented.
