The 2022 Plasma Roadmap: low temperature plasma science and technology

TLDR

Low‑temperature plasma science has positively impacted society, and the 2022 Roadmap—compiled by 41 experts from 21 countries—outlines key challenges and future directions for the field. The roadmap aims to guide the next 5–10 years of research and technology development in low‑temperature plasma science and technology. It introduces new emphasis on plasma‑enabled additive manufacturing, soft materials, electrification of chemical conversions, propulsion, extreme regimes, hypersonics, data‑driven science, and COVID‑19 mitigation.

Abstract

Abstract The 2022 Roadmap is the next update in the series of Plasma Roadmaps published by Journal of Physics D with the intent to identify important outstanding challenges in the field of low-temperature plasma (LTP) physics and technology. The format of the Roadmap is the same as the previous Roadmaps representing the visions of 41 leading experts representing 21 countries and five continents in the various sub-fields of LTP science and technology. In recognition of the evolution in the field, several new topics have been introduced or given more prominence. These new topics and emphasis highlight increased interests in plasma-enabled additive manufacturing, soft materials, electrification of chemical conversions, plasma propulsion, extreme plasma regimes, plasmas in hypersonics, data-driven plasma science and technology and the contribution of LTP to combat COVID-19. In the last few decades, LTP science and technology has made a tremendously positive impact on our society. It is our hope that this roadmap will help continue this excellent track record over the next 5–10 years.
