Ink formulations for flexographic printing of high-resolution conducting patterns

摘要

Systems and methods disclosed herein are directed towards flexographic printing of microscopic high resolution conductive patterns (HRCP). These HRCP may be printed using one or more formulations for high polarity and stable viscosity inks for use in the flexographic printing process. The inks may be water permeable, UV curable, and configured to resist loss of integrity when exposed to water and atmospheric moisture.

主权项

1. A method of flexographically manufacturing a high resolution conductive pattern comprising:
flexographically printing a first pattern on a substrate using an ink, wherein the first pattern includes a plurality of lines, and wherein each line of the plurality of lines is between 1 micron-25 microns wide; wherein the ink includes:
a water-compatible polymer including Polyethylene glycol diacrylate;a plating catalyst;a photoinitiator including thioxanthen-9-one; anda plurality of nano-fibers; curing the first pattern, by least partially solidifying the printed pattern; and plating the first pattern to form a conductive pattern.
