摘要

导电墨水的功能化是通过过氧化氢(H2O2)分解银纳米粒子(AgNPs)表面来实现的。使用这种生态友好型化学试剂制备的墨水在结构、化学和形态上都有特征,显示出具有合适特性的稳定 AgNPs 的存在,并且没有残留污染。这种可溶液加工的墨水的导电性在柔性相纸基底上设计的图案上得到了证明,该图案是使用可充笔的钢笔作为印刷机制来制造简单的印刷电路板(PCB)。测试系统的功能性和耐用性在各种机械限制条件下得到了验证,目的是基本再现柔性电子设备的正常工作条件。研究结果表明,这些基于 AgNP 的墨水可直接应用于喷墨打印技术,从而为在墨水制备过程中使用更环保的化学品铺平了道路。

Solution-Processable and Eco-Friendly Functionalization of Conductive Silver Nanoparticles Inks for Printable Electronics
The functionalization of conductive inks has been carried out through the decomposition of hydrogen peroxide (H2O2) onto the surface of silver nanoparticles (AgNPs). The ink prepared using this eco-friendly chemical reagent has been characterized structurally, chemically, and morphologically, showing the presence of stable AgNPs with suitable properties as well as the absence of residual contamination. The electrical conductivity of such a solution-processable ink is evidenced for patterns designed on flexible photographic paper substrates, using a refillable fountain pen that is implemented as a printing mechanism for the fabrication of simple printed circuit boards (PCBs). The functionality and durability of the tested systems are demonstrated under various mechanical constraints, aiming to basically reproduce the normal operation conditions of flexible electronic devices. The obtained results indicate that the implementation of these AgNP-based inks is relevant for direct applications in inkjet printing technology, thus paving the way for the use of greener chemicals in ink preparation.
