a Optical microscopy images of patterned Ag thin films obtained using a pneumatic dispenser (left) and an EHD printer (right). The insets are the corresponding optical images of printed s-MVDL patterns. b Surface profiles after the sequential processes of s-MVDL printing, Ag thermal evaporation, and rinsing with acetone. c Schematic illustration of the transition zone formation at the edge of printed s-MVDLs. d Surface topography images measured by AFM and the corresponding edge profiles after surface treatment with APTES and FOTS. e 3D surface topography image measured by AFM and the corresponding edge profile of the Ag thin film. A minimum feature size of <8 µm was achieved with the EHD-printed s-MVDL on the APTES-treated glass substrate.
