Abstract:
The latest progress in atmospheric pressure plasma jet (APPJ) and its applications were tentatively reviewed. The discussions centered on:i) the advantages over the conventional dielectric barrier discharge (DBD), such as the generation of highly active, non-equilibrium, low-temperature plasma in open space, instead of in a narrow discharge gap; ii) the structures and properties of the four typical APPJs, including the single-needle, needle-ring, single/double-ring and micro-cavity; and iii) the hot-spot research subjects, including but not limited to the structure optimization, diagnosis of highly active particles, interaction of the plasma with different materials, and applications. In addition, the major technical problems and possible solutions and development trends of APPJ were briefly discussed in a thought provoking way.
