Abstract The functionality of an effective metal NPs based ink in inkjet printing depends on its ability to achieve high mass concentration as well as suitable rheological properties for stable printability. In this work, AuNPs synthesized by USP were successfully formulated in inks of varying [Au] using PVP40 as stabilizer and DI water as solvent. The influence of the increasing [Au] on the rheological, flow and wetting behavior were investigated for requisite printable characteristics. Thermo-physical characterization was carried out on the optimized concentrated AuNPs ink using TGA, DLS, SEM and EDX techniques.

用于低成本纸基传感器喷墨打印的基于 AuNPs 的墨水的表征

摘要 基于金属纳米颗粒的油墨在喷墨印刷中的功能取决于其实现高质量浓度的能力以及稳定的印刷适性的合适流变特性。在这项工作中,使用 PVP40 作为稳定剂和去离子水作为溶剂,通过 USP 合成的 AuNPs 成功地配制在不同 [Au] 的油墨中。研究了增加 [Au] 对流变、流动和润湿行为的影响,以获得必要的可印刷特性。使用 TGA、DLS、SEM 和 EDX 技术对优化的浓缩 AuNPs 墨水进行热物理表征。
