Abstract Title

Understanding the Effects of Plasma Parameters on Plasma-Jet Printed Material Films

Additional Funding Sources

This project was made possible by the NSF Idaho EPSCoR Program and by the National Science Foundation under Award No. OIA-1757324. This project was also supported by a 2018-2019 STEM Undergraduate Research Grant from the Higher Education Research Council.

Abstract

The demand for consistent additive manufacturing processes for biosensors that make use of flexible substrates is increasingly desired. Recent work has demonstrated a strong candidate for such processing is likely a plasma jet printing process. Optimization of the plasma jet printing process requires investigating the effects of different plasmas and flow rates, nanomaterial inks, and substrates on print quality and material properties. In this work, we examine the effects of varying parameters for argon plasma and nitrogen plasma on the conductivity of four-point structures printed on polyamide substrates. Print quality is verified through imaging the samples via scanning electron microscopy and examining the atomic spectra. Our future work involves the characterization of other nanoparticle inks and further demonstrating plasma jet printing as a cost effective, time efficient, and viable process.
