This paper introduces a method to prepare copper nanoparticles in a two-phase water/xylene system, to be used in the fabrication of ink with high conductivity for printed electronics. Copper conductive inks were obtained simply by extracting the xylene layer containing copper nanoparticles from the reaction system. The particles are monodisperse and range in size from 8 to 29 nm and have no direct contact with air, from nucleation to the preparation of inks. Conductive films prepared using the inks have relatively low resistivity after sintering, which enables their application in electronic devices.

一种在两相水/二甲苯系统中用于印刷电子的铜导电油墨的制备方法

本文介绍了一种在两相水/二甲苯体系中制备铜纳米颗粒的方法，该方法可用于制造印刷电子产品的高导电性油墨。简单地通过从反应体系中提取含有铜纳米颗粒的二甲苯层就可以得到铜导电油墨。颗粒是单分散的，尺寸范围为8到29 nm，并且从成核到制备油墨均不与空气直接接触。使用油墨制备的导电膜在烧结后具有相对低的电阻率，这使得它们可以在电子设备中应用。
