Electrohydrodynamic Nanopatterning: A Novel Solvent-Assisted Technique for Unconventional Substrates

Self-Driven, Monopolar Electrohydrodynamic Printing via Dielectric Nanoparticle Layer

“…Despite its advantages, EHD printing has not been developed to its full potential for high-precision manufacturing on shaped nonconductors due to critical challenges. These include unstable or insufficient electric field generation caused by spatially varying profile heights, as well as the entrapment and accumulation of residual charges inside deposited inks, which can interrupt follow-on printing behavior. − Recently, several pioneering explorations have been attempted to bypass one or both of the issues, including applying alternating voltages, , adopting a charge elimination module, introducing reversed nozzle-ground electrodes, dynamically adjusting applied potential, etc. Dynamic voltage adjustment is still necessary when printing on curved dielectrics.…”
