Abstract Scope |
Electrohydrodynamic (EHD) printing is a manufacturing technique that enables printing of complex geometries and designs by utilizing an electrical potential difference to initiate ink movement. One use of EHD printing is to print conductive electronics with metallic ink, which can enable tunable thermal and electrical properties. This work seeks to establish a reliable mode of E-jet printing silver ink with high quality in zero gravity, since EHD printing does not require gravity to function. To achieve this, a novel synthesis and formulation method of EHD ink has been established. 2-hydroxyethyl cellulose (HEC) is utilized as a backbone for silver nanoparticles, serving as a stabilizer and a lifetime extender of unprinted silver ink. HEC also prevents silver nanoparticle aggregation, ensuring a stable network and enabling good conductivity. After printing, the ink is sintered to remove the HEC, leaving a stable network of silver particles. |
