Printing nano-ink with platinum nanoparticles to generate conductive microstructures for electronics on different types of substrates has gained increasing interest in recent years. To solve the problem of the low conductivity of platinum (Pt) nano-ink, we synthesized chemically pure Pt nanoparticles with sizes of 18.2 ± 9.0 nm by spark discharge method. A low toxic solvent, ethylene glycol with water, was used to ensure the aggregation stability of Pt nanoparticles. Polyvinylpyrrolidone was used as an adhesive additive and binder in the nano-ink. Narrow and conductive Pt lines were generated by aerosol jet printing technology. The resistivity of the Pt lines sintered at 750 °C on alumina substrate was found to exceed the bulk Pt by about 13%. Moreover, the Pt film fabricated on polymer substrates has demonstrated excellent mechanical flexibility in terms of twisting tests.
近年来，用含铂纳米颗粒的纳米墨水在不同类型的基板上印刷以生成用于电子产品的导电微结构越来越受到关注。为了解决铂（Pt）纳米墨水导电性低的问题，我们通过火花放电法合成了尺寸为18.2±9.0nm的化学纯铂纳米颗粒。使用低毒溶剂乙二醇与水来确保铂纳米颗粒的聚集稳定性。聚乙烯吡咯烷酮用作纳米墨水中的粘合剂添加剂和粘结剂。通过气溶胶喷射印刷技术生成了窄的导电铂线。发现在氧化铝基板上于750°C烧结的铂线的电阻率比块状铂高出约13%。此外，在聚合物基板上制备的铂膜在扭转测试方面表现出优异的机械柔韧性。
