开发了一种有效而简便的方法，成功地合成了粒径为10 nm的近均匀银纳米颗粒(AgNPs)，并证明了在喷墨打印柔性电子产品中实现了AgNPs的室温烧结。在这种体系中，利用一系列不同链长的烷基胺作为封端分子，可控地合成出平均粒径分别为8.6±0.9、8.9±81.2和9.2±1.6 nm的均匀的AgNPs，这些超小的纳米颗粒非常有利于获得良好的印刷流畅性。基于所合成的AgNPs，利用喷墨打印技术成功地制作了一系列柔性电路。经浸渍处理后，AgNPs表面的封端分子优先溶解在甲醇溶液中，在室温下实现了自发团聚和聚集。这些聚集的AgNPs在31.6x-26.5xμΩ/cm的范围内表现出优异的可控性、优异的稳定性和低电阻率，在为光电子器件组装量身定做的应用中将具有巨大的潜力。
An effective and facile strategy was developed to successfully synthesize nearly uniform silver nanoparticles (AgNPs) with particle size of <10 nm, and demonstrated to achieve the sintering of AgNPs at room temperature for inkjet-printed flexible electronics. In such system, a series of different chain-length alkylamines were exploited as capped molecules to controllable synthesis of uniform AgNPs with the mean nanoparticle size in rang of 8.6 ± 0.9, 8.9 ± 1.2 and 9.2 ± 1.6 nm, and these ultra-small nanoparticles were very favorable to attain an excellent printing fluency. Based on the as-synthesized AgNPs, a sequence of flexible electrocircuits was successfully fabricated by ink-jet printing technique. After the dipped treatment, the printed AgNPs were achieved to spontaneous coalescence and aggregation at room temperature induced by preferential dissolution of capped molecules on AgNPs surfaces into methanol solution. These aggregated AgNPs demonstrated superior controllability, excellent stability and low resistivity in the range of 31.6–26.5 μΩ cm, and would have enormous potential in the application to be tailored for assembly of optoelectronics devices.
