The authors drive a plasma-induced reduction reaction of the gold precursor by alternating current (AC)-driven atmospheric pressure plasma at the plasma-liquid interface. They systematically study the plasma-induced reaction at the plasma-liquid interface and observe that the reduction reaction is a proportionality relationship to the root mean square current of AC-driven atmospheric pressure plasma. Here, the technique has been applied to the plasma-polymeric film interface and demonstrates a direct writing technique to create the patterned metal nanoparticles. The authors find that the pattern properties are significantly related to the absorbed de-ionized (DI) water in the polymeric film. To prove their conceptual idea, the authors newly design an electrospun mat made of poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) and poly(styrene-block-butadiene-block-styrene) and control the absorption ability of de-ionized water and ethanol in a polymeric film. The results demonstrate that the absorbed DI water plays a key role in the plasma-induced reaction at the plasma-polymeric film.

交流驱动大气压等离子体在等离子体-液体和等离子体-聚合物薄膜界面处的等离子体诱导反应

作者通过交流电 (AC) 驱动的大气压等离子体在等离子体 - 液体界面驱动金前驱体的等离子体诱导还原反应。他们系统地研究了等离子体-液体界面处的等离子体诱导反应，并观察到还原反应与交流驱动的大气压等离子体的均方根电流成比例关系。在这里，该技术已应用于等离子体-聚合物薄膜界面，并展示了一种直接写入技术来创建图案化金属纳米颗粒。作者发现图案特性与聚合物薄膜中吸收的去离子 (DI) 水显着相关。为了证明他们的概念，作者新设计了一种由聚（乙二醇）-嵌段-聚（丙二醇）-嵌段-聚（乙二醇）和聚（苯乙烯-嵌段-丁二烯-嵌段-苯乙烯）制成的电纺垫，并控制了对de的吸收能力。 - 聚合物薄膜中的离子水和乙醇。结果表明，吸收的去离子水在等离子体-聚合物膜的等离子体诱导反应中起关键作用。
