我们开发了一种纳米化学反应器的制造方法和液体填充方法，该反应器使用专门为混合和反应设计的Y形纳米通道。为了减少压力损失并利用纳米通道的特性，在纳米通道旁边制作入口微通道。我们研究了纳米通道中的所有初始液体填充方法，确保不存在可能因毛细管压力而导致流动堆栈的气泡。在我们的方法中，微通道和纳米通道充满了二氧化碳，并且利用二氧化碳的高溶解度溶解了初始液体引入期间剩余的空气。我们建议利用这些制造和液体引入技术可以实现纳米空间中的化学反应。
We developed a fabrication method and a liquid filling method for a nano chemical reactor that used Y-shaped nanochannels specially designed for mixing and reacting. In order to reduce the pressure loss and to utilize the characteristics of the nanochannel, inlet microchannels were fabricated just beside the nanochannels. We investigated all initial liquid filling method into the nanochannels that ensured there were no air bubbles that could cause a flow stack due to the capillary pressure. In our method, the micro- and nanochannels were filled with carbon dioxide and any remaining air during the initial liquid introduction was dissolved utilizing the high solubility of carbon dioxide. We propose that chemical reactions in nanospaces can be realized by utilizing these fabrication and liquid introduction techniques.
