| 제목 | Atmospheric-Pressure Microplasma for Novel Plasma-Electrochemical Process: Synthesis and Assembly of Nanomaterials |
| 초록 | Recently, plasmas formed at sub-millimeter spatial scales, microplasmas, operate stably and close to non-thermally at atmospheric pressure and are a source of ions, electrons, and other electronically excited states at ambient conditions. Overall, these features make microplasmas suitable for novel electrochemical applications where gas-phase species (e.g. electrons) in the plasma can directly interact with ionic aqueous electrolytes to initiate redox reactions. Here, we will present several examples of plasma electrochemical reactions for nanomaterial synthesis and patterning (direct write, lithography, directed assembly). Metal cations in solution such as Ag+ are electrochemically reduced by the plasma to solid metal, resulting in the formation of metal nanoparticles without any chemical reducing agent. Details of these various approaches will be discussed in detail, including materials characterization and potential applications. |
