Inkjet Printing Involving Palladium Alkanethiolates and Carbon Nanotubes Functionalized with Single-Strand DNA
Abstract:Pd hexadecanethiolate and Pd butanethiolate precursors as well as single-walled carbon nanotubes (SWCNTS) functionalized with single-strand DNA (ssDNA) were patterned using inkjet printing techniques to form metallic Pd interconnects upon thermolysis and circuit elements, respectively. Issues involved with printing these materials were addressed and overcome. Patterns with lateral dimensions of ≈50 μm were produced. The surface morphology of the Pd interconnects was examined using SEM. By printing 4-probe pattern of Pd alkanethiolates, the resistance as a function precursor concentration was determined, allowing estimates for the resistivity of the printed interconnects. A line trace containing an aqueous suspension of SWCNTs-ssDNA was inkjet printed for resistivity estimates and contacted with Pd pads.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
