描述了一种简单的合成稳定的银纳米颗粒的方法，其颗粒尺寸为10 nm。该合成包括在甲苯中用取代肼(如PhNHNH2)还原醋酸银，在25−60°C的甲苯中，如C16H33NH2，旋涂薄膜或烷基胺稳定的银纳米颗粒的印刷电子特征可以很容易地在120−160°C转化为导电性为2−4×104S cm-1的高导电膜或元件。具有这种性质的印刷银源/漏电极的有机薄膜晶体管表现出与使用真空沉积银电极的器件类似的场效应晶体管特性。
A facile synthesis of stable silver nanoparticles having a particle size of <10 nm is described. The synthesis involved reduction of silver acetate with a substituted hydrazine, such as PhNHNH2, in the presence of a 1-alkylamine, such as C16H33NH2, in toluene at 25−60 °C. Spin-coated thin films or printed electronic features of alkylamine-stabilized silver nanoparticles could be easily converted at 120−160 °C into highly conductive films or elements with conductivity of 2−4 × 104S cm-1. Organic thin-film transistors with printed silver source/drain electrodes of this nature exhibited field-effect transistor properties which are similar to those of the devices using vacuum-deposited silver electrodes.
